A lot or a little?

The parents' guide to what's in this book.

Educational Value

These books are packed with facts about history, geography, ecology, biology and more. They're also full of outlandish gadgets with no scientific basis whatsoever, which even if readers can't always tell if the gadgets exist in our world, are great for the imagination.


Positive Messages

Jack and the GPF are all about helping people, being kind, and righting wrongs, and Jack's fearless, earnest adventures can inspire readers to take action in their own lives.

Positive Role Models & Representations

With the exception of the designated villains, every person -- adult and child -- Jack encounters is kind and honest, and wants to help him on his quests, even if they've never met him before.

Violence & Scariness

Jack gets into some sketchy situations, but that's the premise of these adventures. His life is threatened in every story, but he always emerges unscathed, and the tension level is appropriate for this age group.


What parents need to know

Parents need to know that Elizabeth Singer Hunt's Secret Agent Jack Stalwart series is full of fast-paced adventures, nifty gadgets, and a kindhearted hero who tries to save the world without letting his parents know he's left the house. It's Mission: Impossible with an early bedtime, simpler assignments, and far less ego. The stories are tense, and Jack almost dies in every book, but readers will probably never be afraid he'll actually be killed. There are lots of facts about the places he travels and the animals he encounters, and fun, boundless optimism: A 9-year-old travels through time and space to solve international crimes, unconcerned about his own safety, and completely confident in his ability to do it alone.

What's the story?

In the SECRET AGENT JACK STALWART series, 9-year-old Jack is a member of the Global Protection Force (GPF), solving thrilling international crimes, flying through time and space, using an absurd number of gadgets in his spy backpack and always getting home one minute after he left his room via a portal in the map on his wall. His older brother, Max, is also a member of the GPF, and Jack is trying to find him without letting his parents know Max is missing and not living at a Swiss boarding school. Jack uses his brother as inspiration to get out of tough situations -- like when he's chased through Times Square by a dinosaur recreated from the DNA in a stolen leg bone -- and friendly with everyone he meets.

Is it any good?

The premise is pure fantasy, and it is great fun to read. Jack gets stuck underwater in a swarm of jellyfish and sharks? No problem. He uses a rebreather, shoots a dart filled with blood to distract the sharks, and summons his underwater transport vehicle. Problem solved and he's off to save a hostage. The outcome of each story and Jack's safe return is never in doubt; the delight is in getting there, and the Secret Agent Jack Stalwart Series is captivating page-turners for readers new to longer chapter books.
