An extract:

‘Then why would you mess around with a sperm donor and IVF and all that rigmarole,’ Christos returned, ‘when you have the ideal, the ultimate, the paragon, the epitome, sitting right here?’

She blinked at him. Blinked again. What, exactly, was he trying to say?

‘Me, Lana,’ he explained, and now she heard the humour in his voice again, and she felt as if something in her had settled, righted. This was the man she knew. Trusted. Liked.

‘You.’ She raised her eyebrows, smiled a little.

She wasn’t flirting, absolutely not, but…she liked having him back the way he normally was—funny, wry, affectionate, unthreatening. It made something spark inside her, turn fizzy…although she still hadn’t completely cottoned on to what he was suggesting.

‘Yes. Me,’ he reiterated. ‘And you. Having a baby—and a family—the old-fashioned way.’

It genuinely hadn’t crossed her mind. Christos could see that right off. The way her eyes widened with shock and her expression turned dazed, her lips parting slightly as she simply stared at him.

‘You aren’t serious,’ she finally said, her voice little more than a whisper.

Christos would have been offended, except he knew Lana too well for that. Attraction wasn’t the problem here. He’d always felt it from her, like a live wire they had both made sure never to touch. Lana might not yet have admitted it to herself, but it was there. He wasn’t wrong about that.

As for him…well, that definitely wasn’t a problem, either. It never had been. Even when he’d agreed to the no-sex rule, he’d known he was attracted to her. He’d even wondered if one day Lana might change her mind, and he’d known, right from the beginning, that he would always be amenable…as well as patient. But now?

‘I am absolutely serious,’ he told her. ‘We’re married. You want a baby. It turns out I might, too, somewhat to my surprise, it’s true. Why wouldn’t we do it the way people have been doing it for millennia?’

‘Because…’ She shook her head, her eyes flashing with both humour and ire. ‘That is far more complicated than what I was suggesting!’

Bride Of Betrayal by Abby Green

💓 Forced proximity

An extract:

Leaning against the doorframe, I folded my arms.

‘Am I interrupting anything?’

Her expression was instantly guarded, but her chin lifted in unconscious challenge. She dropped her hand from the frame. ‘No. I was just having a look around.’

Little liar.

‘Sure you were.’ I grinned. ‘If you want the safe, it’s behind that picture and, yes, the necklace is inside.’

 ‘I wasn’t—’

‘Yeah, we went through that last night.’ Pushing myself away from the doorframe, I strolled calmly over to where she stood and pulled the picture away from the wall to reveal the safe. The lock was biometric so I put my thumb on the pad and the lock flashed green as it disengaged. I pulled open the door and reached inside for the sleek black jewellery case that held the necklace.

She watched me, her expression opaque, but I could tell by the way she blinked that she was surprised. That was a mannerism I remembered from last night, just as I remembered everything about last night—from the way she’d moaned when I’d licked her, to the sob of release when I’d made her come all over my cock.

The way I was going to make her come again. Maybe soon. And all I could think about was how that guarded gaze of hers had splintered under my touch like a cheap paste jewel, revealing heat and passion hot as lava. She was like my safe. Only the right touch could open her up.

I held out the box to her. ‘This what you’re looking for?’

She blinked again, rapidly, glancing at the box then back at me, but made no move to take it. So I flicked it open so she could see the intricate loops and coils of diamonds that formed the neck piece and the rubies that fell from it like red rain on silver chains. The Red Queen, finally.

Her eyes widened as she glanced at it, then back at me. ‘Beautiful, isn’t it?’ I took the necklace out, discarding the box onto the floor, and held it up, the weight heavy in my hands. ‘It was made for a queen, which is what gave it its name.’ The light caught the rubies, sending them burning, glittering in the fascinating way jewels did, but she didn’t stare at it. She looked at me instead. Which told me something else about her: it wasn’t jewels per se that she was interested in, not the way some people were. I’d seen enough of that to recognise the glint some people got in their eyes when confronted with a piece they wanted.

Greedy. Possessive.

No, my little thief wasn’t looking at the jewel like that at all. That greedy, possessive glint in her eyes right now was all for me.

An extract:

‘This is Georgie…’

Georgie smiled stiffly, bewildered.

‘Georgie, this is Sophia, my ex-wife.’

The pressure on her waist tightened. Georgie had no idea what was happening but, alert to her status of trespasser who could get in a whole heap of trouble, she kept smiling politely and hoping that things would get clearer than mud.

‘What is a woman doing here?’

‘She’s surprised me with a visit.’

He looked down at her and Georgie, in turn, looked up and up and up at him.

His dark eyes were pseudo tender, not fooling her for a second that his thoughts were anything like tender because the tacit warning in their dark depths was unmissable. At least to her.

‘Haven’t you, my darling? Surprised me with a visit and what a glorious surprise.’

Georgie could have got lost in the sexy, husky timbre of his voice.

‘She has a key to the chalet? Since when do you give women keys to your houses?’

We’re supposed to be an item… For whatever mysterious reason, Georgie knew that she had been suddenly thrust into some kind of role that she was expected to play. She also knew that the deck wasn’t stacked in her favour when it came to having a choice in the matter.

He’d mentioned jail.

She watched the way he half turned towards the shrill voice before resting his eyes on her and, in that instant, Georgie read something, felt something. Resignation…was that it? Or maybe the patience of a long-suffering man who had reached a point of desperate measures.

She couldn’t put her finger on any of the feelings that raced through her, but she did know, with some weird but very definite sixth sense, that he was a fair guy even though he’d had no trouble in blackmailing her into doing what he wanted.

She wondered how that made sense.
