All I Want Is You by Fallon Ballard

Bitter exes. Professional rivals. Just one bed.
What could go wrong?

Jessica Carrington always wanted her own happily ever after. But, until that happens, she spends her days as a small-time romance writer, penning satisfying Happily Ever Afters to soothe the heartache left by her ex-boyfriend Nick Matthews, a fellow romance writer and now her biggest rival, who has found success writing love stories without happy endings. It's clearly what he's good at, after all . . .

So, when their professional obligations find them snowed in - and forced to share a room! - at the same remote inn a few days before Christmas, Jess and Nick are both fuming. But what's more fitting for two romantic writers in a slump? And when they realise the friction between them might be the only cure for their writer's block, they decide to turn their frustration into fiction . . . and the pages start flying.

Jess can't shake the feeling that Nick is the last guy on earth she should be falling for (again), but, as they both finally get back in their flow, is he actually all she wants for Christmas?
