Magpie - Elizabeth Day

When Marisa meets Jake, everything falls into place. But then their new lodger Kate arrives. Something isn't right about her.

It's the way she looks at Jake, keeps her toothbrush right next to theirs and constantly asks questions about the baby they are trying for. Or maybe it's all in Marisa's head. That's what Jake thinks.

And she trusts him, doesn't she? But Marisa knows something is wrong, and she is determined to find out why, even if it costs her everything.
