I never thought Wilson could equal THE TOMB, but LEGACIES comes awfully close. In some ways it's even better. The prose is leaner and meaner, and the tone is lighter. Some parts even gave me grins. Jack has lightened up some, but he's still a dude full of contradictions. He can be such a softie with Gia and Vicky, then go out and cold-bloodedly kill somebody, and I believe him both ways.
The plot in LEGACIES is more along the lines of a mystery than THE TOMB, and it kept me guessing all the way. The heroine, Alicia, is a real tough cookie, but you eventually come to know why, and you really feel for her. (As a bonus, I think I found a link to SIBS, one of Wilson's other novels.)
If I have a quibble, I'd say I would have preferred a supernatural element in the story, but that's just a personal thing. All in all, I haven't enjoyed a novel this much in a long time. Highly recommended.
