The Infinite Sea

I flipped a lot between 2 and 3 stars. I really enjoyed the story, but was increasingly irritated by how it was told.
I didn't read this back to bank with the 1st book, so I had to very a feel for the characters again, which is normal. The random switching off characters made this difficult. I felt like a detective for the first half of the book just figuring out who was narrating a specific piece. This was made even worse by the way the author suddenly switched between the characters present and a story from their past. The book took a lot more energy to process then it should have.
Saying all that why did I give it 3 stars? I still want read the next book and see how it ends. As annoying as the writing was at times, the characters still pulled me in. I care how their story ends.
