Destined Hearts - Willow Creek, #4

The last thing Lou expects, when she moves to the small-town home of the grandfather she never knew, is a series of break-ins. Lou just wants to get a fresh start on life, write her mystery novels, and figure out why her mother and grandfather stopped speaking to each other before she was born. But there's another mystery afoot, one that her museum-archivist grandfather may have secretly solved before he died, and someone else is after the answers, too.
Bryce is tired of life as a cop in a town where an exciting day means finding a missing cat and her kittens. He's applied for a transfer somewhere - anywhere - else. But when he's called in to investigate a break-in for a new resident, he discovers he might not be so ready to leave after all, at least not until he's sure she's safe. With Bryce's help, Lou desperately searches for answers in her grandfather's journals, trying to figure out what her grandfather has that someone would want to steal, and where it is so she can get there first.
