This reminds me a lot of Jennifer Armentrout. Not as well written but a fun paranormal romance for those that like the genre. Fun characters and a cheesy plot that isn't exactly original.
Anna doesn't exactly know her past, its all been a secret. All she knows is life in the lab with the four boys downstairs, being kept and genetically altered into who knows what. Nick, Cas, Trev and Sam. When they all escape Anna's life is changed like she never expected...in fact everything she's been told is a lie.
This is definitely a bit of a Mary Sue storyline with the big bad boys being over protective of the damsel in distress. But I really enjoyed it for the most part. Anna annoyed me at times with how naive she is at times.
A fun and not serious read. I am definitely interested enough to continue the series.
