Author Mark Lawrence attempted to run through the alphabet with SFF titles off his shelves and challenged others to try the same. I was a few letters short but I think I did quite well considering a great many of my books are in my mother-in-laws attic!
Abercrombie, Benchley, Clarke, Dahl (Dahl has to be Fantasy, right?)
Ellison, Foster, George (his Trek books are just fab), Harkaway
Pullman, this Rowling newcomer, Stewart, Tolkien
And for the #amwriting crowd, I find these essential resources when writing. Story by Robert McKee should be on every writers shelf
