Demon Walk by Melissa Bowersock

Sixth in the Lacey Fitzpatrick and Sam Firecloud series, the private-investigating duo are asked to get to the bottom of a menacing evil threatening the lives of the San Jan Capistrano mission. A tough nut to crack, this one, as some of the usual methods aren't enough to combat a killer force.

It’s so easy to slip into this duo’s adventures. They’re like old friends, their tales like a comfy sweater or slippers. Better still, their personal relationship is heading in the direction us fans want. 

As always, Bowersock strikes the perfect balance, careful to make this a compelling supernatural mystery without overdoing the romantic elements between Lacey and Sam.

I’m about to do something I very rarely do: dive straight into book 7. I’m not ready to take off those slippers just yet.
