ECHO picked up where Fated ends. But unlike Fated, the second book doesn't dwell more on backstories and information, Echo jumps right into the plot. ECHO centers more on Daire and Dace's dangerous mission to save the Lowerworld from being corrupted by his twin evil brother Cade. The story is told both from Daire and Dace's perspectives. Daire continues with learning her different abilities, surpassing the challenges and understanding what it really means to be a Soul Seeker and understanding herself. A new character, Phyre is introduced, she is shown at the end having a meaningful conversation with her father, which tells us, they have a bigger role in the books to come.

But I really believe what makes ECHO so gripping is the main characters' relationship; their love has become stronger as well as the complications and danger that comes with Daire as a Soul Seeker and Dace as the Echo. It's so heartbreaking to see them perfect for each other but they cannot be together for the greater good.

Daire does a lot of growing in ECHO, in the earlier part, she is naïve and afraid but eventually she becomes confident, braver and the warrior her Abuela believes she should be. Dace opens himself through his own POV. We get to learn his thoughts, his fears, and his love for Daire.

I was actually thinking that Cade would play the Jacob or the bad-boy-who's-in-love-with-Daire part in the second book,ECHO but I was totally wrong. Cade became the personification of evil in this story. I just wish that we got to know more of him, like what's he really thinking, because although he was the topic of the main characters, he doesn't really showing up that much in ECHO.

The descriptions of the elemental song and the majestic scenes make this book entertaining. However, I must admit that there are boring parts but it won't deter a fan from continuing.

This book had lots, and I mean lots of turns and twists. Decisions made, choices undertaken and the consequences that result are all surprising. The book ends with a beautiful and frustrating cliffhanger that reveals nothing but more questions. ECHO will surely make you wish Mystic is out already.

ECHO is an epic, fast-paced, magical page-turner that leaves the reader captivated and enthralled. It ends with chills, shivers, goosebumps and an insatiable want to read what's next!
