Motherhood is Murder by Diana Orgain is the second book in the “Maternal Instincts” mystery series. Publisher: Berkley Prime Crime, March 2010

Nights out are hard to come by for new parents. So when Kate’s new- mommy club, Roo & You, holds a dinner cruise, she and her husband, Jim, leave baby Laurie with Kate’s mom and join the grown-ups for some fine dining on the San Francisco Bay.

But when one of the cofounders of Roo & You takes a fatal spill down a staircase, the police department crashes the party. Suddenly every guest is a suspect and it seems like every mom and her man has a motive. Kate’s on deck to solve the mystery—but a killer’s determined to make her rue the day she joined the first-time-mom’s club…

I enjoyed this book much better than the first one. This time Kate is on a dinner cruise with Jim and one of the moms is found at the bottom of the stairs. While Kate doesn’t have a license to be a PI, with help from her husband, her best friend Paula, her mom and her PI mentor, Kate discovers little dark secrets that someone wants to keep it quiet and is willing to kill again. My rating: 4 stars
