Into Thin Air by Kristina Beck

Fed up with the endless demands of her job, Ellie seeks solitude from the chaos. As if by magic, she finds herself all alone in an exotic hotel. That is, until she meets the gorgeous guest next door. As time melts away, Ellie falls hard for Sam. Then he vanishes into thin air, taking his love with him. When he suddenly reappears, he isn’t the Sam she once knew, but her aching heart tells her otherwise.
Sam finds himself at a crossroads in his soccer career when a permanent injury forces him to make a difficult decision. He thinks seclusion in a luxury hotel is what he needs, until he sees the fiery redhead, Ellie. She has no idea who he is and becomes the woman of his dreams.
Like any vacation, it must come to an end… just not in such a tragic way. Sam thinks he’s responsible for Ellie’s death, and when he discovers she’s alive, she doesn’t greet him with open arms. The relentless fight for her dignity and career threatens to end their passionate reunion.
They said their love was infinite, but anything can change when reality comes crashing down.
