A Sister's Test by Wanda Brunstetter is the second book in the Sisters of Holmes County series. Ruth Hostettler, the younger sister of Grace from A Sister's Secret, the first book, has recently broken up with troubled Luke and seeks the kind of loving marriage that Grace has found with Cleon. When Martin Gingerich starts courting her, they both feel the need to marry immediately, as though something is warning them. The attacks on the Hostettler family farm have continued and ratcheted up in intensity. Someone has it out for this Amish family, and they aren't afraid to take extreme measures. Is it Grace's English ex-boyfriend or Luke, Ruth's ex-boyfriend who is still going through rumspringa? I don't normally read the many Amish Christian fiction books on the market, but this series truly stands out from the rest. There is suspense and mystery along with deep faith and family. It's a real page turner that's impossible to put down. Each member of the family has their own way of dealing with the siege of terror, from the father's quiet acceptance, to youngest sister Martha's detective work. Every character pops off of the page and breathes life into the story. I don't know how I'm going to hold out until July to read the final book in the series, A Sister's Hope, to find out who the attacker is!
