Question Everything by Hilari T. Cohen

Maeve Byrne is on the run.

She’s a hunted woman and she’ll do anything to protect her baby daughter from harm. When she realizes that she’s been found by people who wish her dead, she gets in her car and drives as fast as she can into the night. Unfortunately, all it takes is one unexpected curve in the road for her life to be literally upended.
Kyle Walsh is no stranger to bad luck. On administrative leave from the Boston PD, for an incident surrounding the unauthorized use of his weapon, he witnesses Maeve’s accident and instinct kicks in; he runs to the scene to try and help her. But what he finds just doesn’t add up and he becomes obsessed with figuring out just who this woman is and the story behind why she’s in Boston. As she loses consciousness, she asks him to save her baby, and he hears her distinctive British accent. Kyle is intrigued by this beautiful stranger and is determined to unravel her secrets.
One big problem? Maeve doesn’t remember anything from before the accident; not where she came from, not why she was driving the car or even her name. As she begins to question everything around her, he begins to question whether she’s telling him the truth about any of it.

The other dilemma? He falls in love with her. And once he loses his heart, he wonders if he’s losing his mind, as well…
