Realtor Nikki Marshall has minimal experience with children, but when her friend Laura and her husband are offered a three-day cruise, Nikki promises to care for their twins. Then the unthinkable happens: The couple is stranded for an indefinite period, and Nikki must turn to Laura's brother-in-law, contractor Seth Baxter, for help. Nikki's relationship with Seth has always been rocky at best. But oddly, juggling their busy lives while handling Assignment: Twins (3) improves it radically. Leigh Michaels' latest is sweet, lighthearted fare that will entertain readers who enjoy family-oriented humor.
