There's a storm raging in Eerie-on-Sea. Has the mighty Gargantis come back from the deep...?

When an ancient bottle is found washed up on the beach after a ferocious electrical storm, all the residents of Eerie-on-Sea seem to want it ... but should they in fact fear it? Legend has it that the bottle contains an extraordinary secret that spells doom for the whole of Eerie-on-Sea. Could it be true that the vast sea creature Gargantis has awoken from her slumbers, and is causing the large cracks that are appearing all across the town? Finding themselves entrusted with the bottle, Herbie and Violet discover they will need to ride the terrible storm and pacify the creature if they want to save Eerie-on-Sea from sliding into the ocean and being lost for ever.

4 stars. Gargantis was just as atmospheric and brilliant as Malamander… I especially love the world building the author has created. I swear I can see the town of Eerie-on-Sea and smell the ocean from here.

This is a book you won’t be able to or want to put down! Written cleverly, it is great for all ages with characters you can’t help but love.

I loved this… It was [a] delight to return to Herbert and Violet at Eerie-on-sea. These are aimed at middle grade readers, but they are filled with amazing characters and content that YA and adult readers will enjoy!

Bookish Intoxication

Gargantis was such a treat to read. At 351 pages, I couldn’t help but wonder initially if this would be too long, but the author has such a talent for pacing and humour that those 351 pages flew right by. Gargantis is a fast-paced, action packed adventure that will grab young readers and keep them engrossed until they very end.
