The Man I Thought You Were — Leah Mercer

One fine autumn evening, Anna returns from work and starts making dinner, eager to welcome home her husband, Mark. It's just like any other day in their ten-year, Pinterest-perfect marriage -- until he says he's leaving her.

Discovering that the man she thought she knew better than anyone else is capable of abandoning it all sends Anna reeling. She believed the life they'd built together -- and the bright future they'd imagined -- counted for everything. How can he walk away?

The truth is Mark is battling secrets of his own -- secrets Anna knows nothing about. A painful past and an uncertain future threaten to bring his life down around him -- and he'll do anything not to expose her to that.

But unravelling the past is lonelier than Mark could ever have imagined and, as the days turn to months, Anna worries the separation will break them forever. Can she bring him back from the brink of self-destruction before it's too late, or will she discover that she never really knew him at all?
