Query: Another keeper from Suzanne Brockmann

This book, like its predecessors, is fast-paced, sexy, and fun. It is the fourth in a series that has many readers hooked. The author has taken a minor character from her previous books, the obnoxious computer whiz SEAL Wildcard, and turned him into a terrific lead. The subplots are engaging and well-woven into the story. The book stands well on its own for those who haven't read the first three, but there is a continuing saga of two characters, Sam and Alyssa, that has built (and hooked readers) throughout the earlier books.
