When my daughter was getting into reading, I made a deal with her that I would read anything she recommended. These are some of her favorites:
Christopher Golden's BODY OF EVIDENCE forensic mysteries
Lois Duncan's mysteries, including DAUGHTERS OF EVE, KILLING MR. GRIFFIN, I KNOW WHAT YOU DID LAST SUMMER, RANSOM, SUMMER OF FEAR, etc.
The Harry Potter books
The Penderwick books
Jennifer Weiner's Bigfoot series
She liked the Twilight books but I didn't get into them.
