Under A Blue Moon by A.J. Downey

Don’t get too involved is one of the first things they tell you when you join the force. Jeremy Poe has never had a problem with that one until now. He blames it on the magic and persuasion of the blue moon hanging overhead, or maybe it was just the magic of Saylor Grace herself. Either way, he’s satisfied that this is a gamble totally worth taking.

Speaking of gambles, Saylor’s made a huge one by driving her beat-up old car all the way across the country with nothing in her pocket except her raw talent. It was supposed to be a safe bet, it was supposed to be forever… sometimes, ‘forever,’ has a funny way of working out.
