Her Billionaire Ex-Boyfriend Fake Fiancé by Christine Kersey

A billionaire who wants to grant his mother’s dying wish and the only woman who can make it happen.

Librarian Ashleigh Hopkins loves Christmas, which is when she holds a big fundraiser for the Emerald Falls Library. Eager to raise money for more computers, books, and other critical supplies, when the auctioneer announces that a date with Ashleigh is on the auction block, she goes with it. Too bad her ex casts the winning bid.
Billionaire Chase Matthews hadn’t planned on spending December in Emerald Falls. And he certainly hadn’t planned on offering the winning bid for a date with his ex. But now that both of those things have happened, he’ll have to deal with the fallout.
When Chase tells Ashleigh that his mother is dying and that her only wish is to see him happily engaged, he makes her an offer she can’t refuse. But will her wounded heart be able to remember that this is all pretend?
