2006 books
23) Philip K. Dick, Dr. Futurity, 1960
An awkward time travel tale that also shows PKD really didn't do adventure tales very well, and the characterisation is minimal at best. A doctor gets flung forwards then backwards in time, caught up in a plan to prevent the European incursion into North America in the sixteenth century. Unmemorable and far too convoluted for my personal liking.
