Mancandy Crush by Tawna Fenske

Josh Mattis is totally over getting his heart stomped six years ago, so what’s with the mule kick to the chest when he spots the girl who ghosted him? Turns out she’s not his teenage fling, but her twin sister—and she needs a fake date to her cousin’s wedding.
Valerie Vincent would rather shove sewing needles in her eyes than have one more person tell her she needs adventure. All she needs is a quiet reading nook and a chance to enjoy Bree’s quirky Christmas nuptials in the summer sun at Ponderosa Resort. Okay, she’d also like to skip the pitying looks when her twin trots out her fab new fiancé, but Val can fix all that with one rugged river guide who’s happy to play her arm candy.
As Josh and Val bond over weird eggnog and messed-up mistletoe hunts, the July sun isn’t the only source of scorching heat. Will the past be a blast of icy cold reality, or can their fling last longer than a peppermint fudgesicle on a hot day?
