"Jack Stalwart has become my precocious 5.5-year old son's favorite bedtime story. If you're looking beyond Harry Potter, this is a great adventure series sure to capture your youngter's imagination. We received 2 Jack Stalwart books as gifts and now are purchasing the rest of the set."

"I just wish our local library would discover this series. We have been searching for another series for my son -- he devoured all the 'A-Z' Mysteries and then had trouble deciding on the next series of books that could capture his imagination in the same way. These books do it. He devours them -- challenging his reading skills, but making it so fun he doesn't even know it. I'm sure girls would love these books, too, but they are especially great for little boys who already have a sense that secret agents are cool. "

"My son just loves all of these books. The latest, book #4, he read in about 2 hours. He loves the places, the adventure and the gadgets. I like them because, they are not scary-violent or creepy. He loves to talk about the cool cities Jack visits. I would love to find another series that is similar."

"A perfect series for my 6-year-old spy-loving-adventure-loving boy. It wasn't boring or painful for me to endure with him either. He enthusiastically read on his own too."

"My 6 year old boy loves this series and can't wait for more. It is great seeing him get so excited about books. Thanks Elizabeth Singer Hunt."
