AMISH COUNTRY REFUGE 

After Hannah Miller's mother is murdered and her sisters go missing, someone comes after her. Now the only way she can survive is to entrench herself in an Amish community…and rely on Lucas Grant, a former police officer who is planning to join the Amish faith, for protection. But finding refuge for Hannah—disguised as Plain at a secluded inn—pulls Lucas back into his old life. And when Lucas discovers the criminals after them may be the people who killed his partner, the mission to take them down becomes personal. With the assailants closing in, though, can Lucas stop them…and finally put his past behind him to start an Amish life with Hannah?
