Hi ForeverBookers, Linger was another great book!
Some spoilers if you haven't read Shiver (book 1) yet.
It starts from where Shiver ended following the same characters. We get to see how Sam starts his life as a human again after so many years as a werewolf. Grace is suffering from an unknown illness that steadily gets worse the further you read on in the book. I thought the author wrote the scenes of her illness well. They were compelling to read.
We also get to read from two new perspectives as well. Isabel, who is mentioned in Shiver and Cole who is a completely new character. Isabel is the werewolf (that died at the end of Shiver's) sister. Cole is a boy band member who was turned into a werewolf. Isabel and Cole are unsure of each other to begin with but they learn to get along.
The story of Linger focuses more on Grace and Sam being separate after Grace's parents catch them in bed together. It's a YA book again so they're not actually doing anything but sleeping together. While they're separated as I put above Grace becomes ill. The one unbelievable thing about this book, for me at least, was that no character could tell what was happening to Grace, when it was really obvious to me and I'm sure most other YA/Adult readers. I don't want to spoil it as it's the main point of the book I feel as well as seeing Grace and Sam on their own.
Overall I liked this book. I gave it 4 stars because of Grace's illness not being figured out when it was really obvious what was happening to her but apart from that this is a great second book in a trilogy. Yes, it had some slower parts but that didn't alter my overall enjoyment of the story.
I'll read the final book in the Mercy Falls Trilogy (Forever) next so stand by for me review of that.
