Syren is Book 5 in the Septimus Heap series
Synopsis (from Amazon)
In the fifth book of this Magykal series, Septimus and his friends find themselves on an island whose secrets are as dark and dangerous as its inhabitants. Septimus Heap returns to the House of Foryx with Spit Fyre to pick up Jenna, Nicko, Snorri, and Beetle. But the journey home does not go well and when Septimus and his friends are caught in a storm, Spit Fyre crashes into the Rokk Lighthouse. They are rescued by the lighthouse keeper who is disturbingly sinister, and who has an equally sinister cat …And all the while, Septimus is trying to fight the strange pull he’s feeling to the island and its mysterious secrets.
There is something about the Septimus Heap series in that it takes a while to really get going, you get hints that it will get exciting but it’s only towards the end that it actually becomes exciting with a gradual build. his was still true of Syren, although I do think it got going a little quicker than the previous books. I think I am enjoying the stories more as we go through the series as well, and whereas before I read the other books without and real anticipation I am actually really looking forward to Darke, I just wish it was out already!
Really my main problem with this series is that it isn’t much of a series in the way the books link together. In some ways this one was linked to the other books, and I can definitely see how it may link to the next book, but it also seems in some ways unneccessary to the series as a whole, and as if Sage was just trying to stretch out the books.
