Bloodhype (1973) is a science fiction novel written by Alan Dean Foster. The book is eleventh chronologically in the Pip and Flinx series, though it was written second, and it is an oddity for the characters since they only appear in the last third of the book. Foster originally started the novel as a stand-alone work, but was encouraged by his publishers to include the characters from his previous novel. Although it was written as a second novel, it logically falls -after- Orphan Star, where he meets the aliens who build him his ship, the Teacher.
