Captain Stewart
Featured Amphibious Submersible
Danger 3.7

Zac Power is about to embark on his first solo mission―finally! And it's almost as cool as playing a guitar solo for millions of screaming fans. For years, top-secret government info has been stored at the bottom of the deepest ocean in the world. And it's been totally safe…until now. The enemy is testing a new submarine that can dive deeper than ever before.

Can Zac find the enemy, protect the top-secret info, and still make it home in time to walk the dog?

About the author

H.I. Larry

124 books30 followers
After three years, it is finally time to lift the lid on the secret identity of the Zac Power series’ best-selling author, H.I. Larry.

Zac Power’s world of adventure and espionage has been immensely successful, with around fifty exciting stories published and over a million copies sold in Australia alone. The ‘H.I. Larry’ pseudonym was used to keep the series consistent (and boringly, ensure that all Zac Power books are catalogued and shelved together!), and readers have long been intrigued by Larry’s secret identity.

The voracious reader demand for more Zac stories required a large writing team comprised of several brilliant Australian authors – many of whom have gone on to create their own fiction. Because of the success of the Zac Power series, and these authors’ rising profiles, Chris Morphew, Hilary Badger and Meredith Badger are now available to speak about their work on the Zac Power series.

H.I. Larry -kollektiivin toinen osa "Syvissä vesissä" (Sanoma, 2012) jatkaa 12-vuotiaan salaisen agentin seikkailuista kertovaa sarjaa. Nyt ollaan huippusalaisen sukellusveneen jäljillä. Sukellusvene kun pystyy sukeltamaan ennätykselliseen 1200 metrin (sic) syvyyteen, mikä pistää miettimään, missä h-vetin umpiossa kirjan kirjoittajat tai suomentajat ovat eläneet.

Lapset tykkäävät, mutta onhan tämä ihan kamalaa huttua niin kökösti kerrotun toimintansa kuin väkinäisen huumorinsa puolesta. Vielä huonompi kuin sarjan ensimmäinen osa, eikä edes yhtä helposti vinkattava.

I enjoyed this short, 10,000-word action adventure.
The pace is fast, there is lots of white space, the font is large, and the characters are engaging.
It's an excellent read for young readers looking for excitement.

This was better than the first but still had issues either way timings and basic science. Line blowing up a submarine as deep as it was but being able to tow it to shore and arrest everyone on board?

I loved this book! The idea of having a young person be a secret agent is great and that is one of a thousand reasons I relished reading the book.

I like the part where he saves a couple because it leads to a funny discovery that he thinks will help, but is unnecessary and makes him want to leave.

Overall, this was a superb short story and must be read by all young people between the ages of 7 and 10!

This book is about a boy who’s name is Zac Power. He is a spy and also a student. He goes to an aquarium for a school trip. Zac thinks is was very boring then his spy senses kick in and he jumps in the aquarium and a shark bites him. Everybody is panicking.


Not the best book ive read, but it was very fun to read. I think its goes well to the series

Zac Powers next mission is in one of the deepest oceans in the world.

Even Gib's subs can't handle the depth. But the enemy has invented a new sub that can dive deeper than ever before.

Can zac find the enemy, and protect the top secret information stored on the seabed? - Te Ahu

A spy adventure story featuring 12 year old Zac Power. Kind of reminded me of a sort-of cheesy YTV kids Tv special but I think that it's an appealing read for 8 - 11 year olds.

Samaa kamaa ykkösen kanssa - tosin mukana hai-allas, jättiläiskalmari, supersukellusvene ja koe koralleista.

Captain Stewart sounds like a boys name but it is a girl. It is so funny when zac screamed in the submersible.
