John Christopher has died at age 89.  Best known for his Tripods trilogy, his science fiction for young adults, Christopher also wrote for adults.

The Tripods trilogy was first published in the late 1960s and when I was a youth librarian in the early 90s was still considered one of the top reads for teens looking for pure science fiction.  Happily, there are newer options out there for science fiction fans now, yet I wouldn’t hesitate to hand a reader the Tripods.
