Super entertaining read and it's a bit unique genre-blending: combines medical forensic mystery, bit of horror/adventure with time travel and a bit of romance. It's also super long - hence split into 2 books for the first in the series.
This second book focused on more murder mysteries and setting up for the other two series for the other two sisters.
Not bad but dragged forever with unnecessary twists that makes the story feel like it has an episodic filler. There's also some plot threads left which I assume will be picked up in other books in the story.
