Your Hand in Mine (Blackbird 2) by Lily Foster

Skylar Perillo has been living a perfectly ordinary life in an ordinary small town, but nothing is as it seems. No, her life isn’t ordinary, and it’s a far cry from perfect. Leaving the one place she’s ever called home is the only way forward, but it’s like her mother used to say: The grass isn’t always greener.

When a job as a nanny literally comes to find Skylar, she has no choice but to take it, even if it means working for the seriously uptight grump who’s already gotten under her skin.
But those old pearls of wisdom do ring true, because when it comes to Leo Hale, Skylar’s going to learn that you can’t judge a book by its cover, and that it really is darkest before the dawn.
