The Hardy Boys book series!!! (it’s like Nancy Drew but… with boys! so he’ll like that better) and there are TONS of them.

i put something about the books too!

the series of unfortunate events by lemony snicket
they really kept me busy in 4-5th grade! (5th-6th grade level)
–Violet, Sunny and Klaus Baudelaire are very intelligent children. After their wealthy parents sudden and suspicious death in a fire that also burnt down their home the children are sent to live with count olaf. Soon enough they dicover that count olaf is planning to kill them and claim their inherited fourtune. The children outwit olaf’s first plan to kill them and Olaf looses custody over them. They are then sent to live with Uncle Monty ,another distant relative, but count olaf refuses to give up and continues to try and execute his plans to get his hands on the childrens fortune. Thus reducing the Baudelaires lives to an ever recourring series of unfortunate events.

or the boxcar children they are mystery books. he’ll like them.(3rd-5th grade level)
–Imagine what it would be like to live in a railroad boxcar with just your brothers and sisters and no adults to help you or take care of you. Meet Henry, Jessie, Violet and Benny Alden — the orphans known as the Boxcar Children — who wind up living in an old red boxcar after their parents have died. Eventually the children’s wealthy grandfather finds them and gives them a wonderful home, but their adventures don’t stop there. They travel to all parts of the country, see exciting places, and become involved in strange and mysterious happenings — sometimes right in their own backyard!

inkheart is also good. and the movie just came out so if he likes it he can see the movie. (5th grade level)
–Inkheart an enchanting fantasy tale about a girl called Meggie. Meggie is a girl the age of twelve who lives in Italy with her father, Mortimer, but Meggie has always called him Mo. Mo is a bookbinder who loves books and so does Meggie, although unlike most fathers he has never read out loud to her since her mother “left”.When Meggie can’t sleep she lays down with a book and reads by candlelight, even though Mo has told her many times not to, when she is sad she reads, and when she has nightmares she runs to mo’s room and reads, nothing allows her to fall asleep better than a book and the sound of Mo’s soft breathing. At night she falls asleep with a book under her pillow and swears that sometimes she can hear it whispering to her. Mo has always told Meggie the truth about everything or so Meggie thinks.

and the bailey school kids. they are AWESOME mystery books. (4th-5th grade level)
The Adventures of the Bailey School Kids (or, simply, The Bailey School Kids) is a best-selling children’s chapter book series by Marcia Thornton Jones and Debbie Dadey. Its main characters are a group of four children (Eddie, Howie, Liza, Melody) who suspect some persons in the stories are popular folk lore or fairy tale characters. For example, in one book they believe a man named Frank who resembles Frankenstein in appearance to actually be the Frankenstein creature himself. In other books they suspect persons to be mythical and folk lore characters such as elves, unicorns, mermaids, Santa Claus, leprechauns, Bigfoot, Cupid, vampires, Martians, werewolves, ghosts, angels, etc

Eragon might be too hard for him. depending on if he reads. its a 5th or 6th grade book but since he doesnt enjoy reading it could be too hard, but you can try.

good luck! =]

The Hardy Boys or The Boxcar Children.

They read my mind on the Hardy Boys thing, They are very good and they will draw you in. There is a series called Bunnicula that’s about an evil vampire bunny. I read it when i was in the third grade and it’s set to a fourth grade level. Oh! I almost forgot! The Mysterious Matter of I.M. Fine! I love that book!!
