Season of the Witch by Sophie H. Morgan

It was a passion neither could forget—until he did.

Tia Hightower isn’t sure how she went from being a powerful witch to fake dating her ex at a winter house party.

For eight years, she has refused to speak Henry Pearlmatter's name unless it has been to curse it. Now, with their family businesses merged, she and her insufferable ex must pretend to be together to secure a wealthy warlock’s investment. Sharing a room—and a bed—with Henry is bad enough. Even worse is that Tia might have had a small potion mishap…and accidentally erased Henry’s memories of her.

Henry might not remember his ex, but it’s clear there’s still something between them. Whatever went wrong in the past, he intends to figure it out. Faking feelings for Tia isn’t exactly difficult, but one thing’s for certain: starlight carnivals and mulled-wine kisses can't change history.

With the threat of Henry’s memories hovering over every stolen moment, their time together is running out. But a little bit of Christmas magic and the snow-melting heat between them have Tia wondering if it’s time to risk her heart once more, even if it's with the warlock who once broke it…
