Thank you Heather Siegel, Stone Tiger Books LLC, and Netgalley for the free ARC in exchange for a review.

It was hard to put this stylistically light, theoretical physics novel down throughout the book, but for different reasons.

About the first half is, as advertised, about a daughter trying to save a mother. It's a beautiful, touching story of strength and conviction. It's also a good lesson in fighting for free speech / thought and exploration of possible truths in the search to save a loved one and to try and understand the nature of reality. Just this, makes it a good recommendation for any teen, if parents are looking for a gift book.

The rest of the book turns into a bit of a cheeseball horror film. Isn't the ghost possession trope, *ahem*, shady and tired by now? The action seemed a bit stale, because of the lame one-liners. And before anyone notices that I'm no longer a teen, and comments that maybe this isn't my genre and I shouldn't be reviewing it; I would have thought the same had I read this at the protagonists age. The contrast in styles was a little startling. And a lot predictable.

I'll say one more good thing; unlike so many of the reviews I read about teen novels these past few years, this one, while perhaps having hints of what could be termed instalove, did not allow the teen romance which blossomed throughout, to take over the story. The protagonists love interest is an integral part of the story.

As I sort of enjoyed the cheesy parts of this novel in a smirking way, I decided to only remove one star, for the odd contrast between the two parts of the book.
