Heather Cashman has created a series that will satisfy the Fantasy and Dystopian lover in you! It did in me without doubt.

Here is the book summary: Your perception will sharpen once you see through a tiger's eyes.
More than five hundred years after the apocalypse, the survivors of off-grid genetic experimentation have refined their mixed DNA to the point that humans and their animal counterparts share physical and mental links. Varying species have divided into districts, living in a tenuous peace under the President of Calem.
Ardana and her tiger ingenium Rijan leave their life of exile and abuse in the Outskirts, setting out with their twin brothers to redeem themselves and become citizens of the Center. But shedding their past isn't as easy as they had hoped. When the system that shunned them becomes embroiled in political conflict and treachery, their unique abilities and experiences from the Outskirts make them invaluable to every faction. The runaways become pawns to friends as well as enemies, and with every step it becomes more difficult to tell which is which.

This book is smarter than your average YA and at first is a bit confusing. There is a lot of information to process at first but Heather Cashman rewards us for the effort. Soon into the story you begin to grasp this new world she has created, lush scenery and complex personalities that capture your mind as well as the over-all political climate that has developed in the five-hundred years since the genetic manipulation of their ancestors.
The empathic link a brother and sister share with their tiger counterparts is a joy to experience. The journey these four have to make in order to secure a better future for themselves is made richer for it. Experiencing the environment through the eyes of human and tiger, brother and sister was a great addition to the story.
In the person of Ardana, you learn of her struggle to avoid commitment of any kind outside of her tiger and brother. The abuse and neglect she suffered growing up in the outskirts have caused her to devote herself in the search for true freedom and any type of commitment to another would destroy that dream.
Her brother Kade is all too aware of Ardana's struggle but has an issue all his own. Ardana believes Kade is destined to become a great leader in Calem but Kade does not believe he can be great.
I think the underlying message of Perception is perception, (lol). How do we see ourselves? How do others see us? Which is real?

I think most readers will enjoy this book and I highly recommend it to lovers of Fantasy!
