I LOVED this book. Even more than Wolf Brother. This is my second reading, I'd forgotten most of it since it had been years and I fell in love with it all over again.
Torak is looking for the cure to a strange illness, but there are some turns of events that make it all interesting. There's intense buildup, there is suspense; unlike Wolf Brother, this time you're never really sure who the enemy is, or if there is one, and what they want, until the end. And then, there's plot twists, reveals and betrayal.
This time you're also introduced to the nautical clans, their traditions and lifestyle (as opposed to the forest clans) and you can tell the author did some extended research on the topic. I'd love to meet Bale from the Seal Clan again in the next books.
However, the same way I did with Wolf Brother, I struggle with the way sceneries are depicted. Lots of times, the way things are described makes no sense to me and I have to reread it again and again to be able to picture it. Sometimes, it's crucial to understand what is going on and what the characters are doing which left me having no idea how they found themselves in such situations more than once (Is it just me? Would love to hear about this from someone who read it). For this reason, I wanted to give it 4.5 stars, but half stars aren't an option and I loved this book too much nonetheless to give it 4 stars.
Also, am I the only one to be extremly surprised Fin-Keddin is only 39 years old? For some reason I imagined him as an old man, barely younger than Saeunn, and pictured him as some type of Dumbledore.
In conclusion I completely recommend it to everyone who's already read Wolf Brother. You won't be disappointed in this sequel.
