Andromeda Strain was my first favorite book. I liked Creighton, up until he came out with "Sphere", a horrible book with an equally awful movie.. I haven't read anything of his since. I might, however, pick this book up...
That's funny. Sphere was the first book I read of his and its the book that turned me on to Crichton. I read most of his novels when I was in 6th grade.
