Everyday A jumps into another body. Each day is different. Along the way he encountered Rhiannon and they fall in love. But both decide it's probably best to not be around each other. Now though Rhiannon questions whether she can be without A. She reaches out to A and what happens next involves the realization that there are other entities like A out there. Only not all have good intentions.

What worked: I really love this series! Think Quantum Leap meets YA. Just like that classic TV series, A jumps into a different body every day. What really works in this series is how Levithan shows the pain and isolation A feels, fearing that there are no similar beings out there. A loves Rhiannon, but fears there is no future for them. Rhiannon looks beyond the female/male identity stereotypes and instead sees A's soul.

There is another entity out there like A, only X has not too great intentions. X uses bodies to the point that he doesn't care if the person he's inhabiting wants it or not. **An interest tidbit X considers himself a 'he' while A is more gender-fluid.

A big question throughout this sequel is about the soul. Is there one? Can it be destroyed or not? When X stays with a host body, what happens to the 'real' person? I really like how readers do see that there are consequences.

There's hints that others like A and X are out there too. It would be great to have companion novels that explores these entities.

Above all the biggest question is what is human? Even though A doesn't have a body, does that mean there isn't any humanity? It is really great to see and compare A with X and see that even though they are both same in one way, they don't share the same intentions. As a matter of fact one could very well be considered without compassion and empathy.

Captivating sequel that questions what identity is and that love knows no barriers.
