Tess Gerritsen’s Gravity is a sort of plague drama, wherein people die by the Space Shuttle-load. The cover says “Better than Chrichton!” which may well be true, but doesn’t seem like quite the compliment they intended it as after his recent works. The story is fairly solid, and though it only really paints a few of the characters as fully three dimensional, there’s enough of interest going on to keep you engaged. A fun read for the idle afternoon you’re wondering how to fill, but probably not worth plugging up your reading queue with if it’s already crowded.
