My Fake Boyfriend Christmas by Gaia Tate

Miles Rivera gets an unexpected call. Old family friends invite him, his parents, and his older brother to spend Christmas at their lake house. The problem? The family friends are the Callahans―parents of Kieran Callahan, Miles’ long-time unrequited crush.
That same guy who pretended to be Miles’ boyfriend to make him feel better. The guy who nearly got killed along with Miles at a serial killer’s house a few months ago. The guy who makes Miles’ insides melt with a sheer look and drives Miles mad with his fake kisses and touches.
Kieran is not planning to show up at the lake house―until he does, and the tension between them spirals to a new level.
And by the way, who are those suit-clad people following them around the snowy town?
