Girls to the Rescue: Young Marian's Adventures in Sherwood Forest by Bruce Lansky & Stephen Mooser, published by Simon & Schuster, is now free at Amazon US.
The Sheriff of Nottingham learned the hard way: don't mess with Maid Marian! This Girls to the Rescue novel tells the exciting tale of thirteen-year-old Maid Marian and her first adventure with young Robin of Loxley (the future Robin Hood).
The Sheriff of Nottingham has thrown Marian's father into the dungeon, and only Marian can save her father from the hangman's noose.
Marian proves herself the cleverest of heroes as she takes on a pack of hungry wolves, murderous thieves, and the Sheriff's loyal soldiers. She also solves a heart-wrenching mystery--the disappearance of her mother, missing for three years and presumed dead.
