The Caldera

 

The Caldera is the 7th book in The BrotherBand series by John Flanagan. 

I did posts on John Flanagan's series Ranger's Apprentice some time ago, big thanks to Tasha for reminding me that I still had to do this series! 

I like this series a tiny bit more then I like the Ranger's Apprentice, because I feel like there's more action and more going on.

Here is the summery

In Hallasholm, Stig is contesting the annual Maktig competition to decide Skandia’s greatest warrior. But a late-night knock on the door brings someone Stig never expected to see again, along with a request the Herons are hard-pressed to refuse: a rescue mission of epic proportions. Across the ocean, the southern city-state of Byzantos is plagued by a crew of pirates who’ve kidnapped the son of Empress Justina. Slipping out of Hallasholm under the cover of darkness, the brotherband sets sail to recover the boy from his kidnappers, heading south to the island of Santorillos where a near-impenetrable fortress stands atop a cliff, surrounded by a lagoon—a caldera—formed by the crater of a volcano.
