Rick Riordan is beloved here as well!!!
My son's 10, and I've been doing the hhhhhmmmmmm....ahhhhmmmmm thing about my scifi/fantasy list (McCaffrey, Eddings, Heinlein, Asimov, etc.)
I'd just decided to go ahead and introduce him to Piers Anthony's Gap & David Eddings (to bypass the sex in Dragonriders for another year ;) Belgariad. 10 books, and he's a slower reader, so that buys me some time before McCaffrey & Heinlein! :D
What he's already read (aside from Percy Jackson, Harry Potter, etc.)
- George's Secret Key to the Universe
- 39 Clues
- Hitchhiker's Guide to the Galaxy (Read aloud = BEST! My bestie read the entire first book over the phone to me when we were in highschool. Much more fun to read aloud than silently. So I carried that on)
- Sherlock Holmes (we're reading one, and watching 2... both old & new versions. New being Sherlock BBC, not Elementary)
- Nero Wolf (mysteries)
What I'm Hemming & Hawing over:
- Stainless Steel Rat series
- A. McCaffrey (RIP)
- Heinlein
