Fantastic book

“I loved the book, and in my case, it's not easy that I like an epic fantasy book (it's the first one I read). One gets to become fond of certain characters (like Fizz) and to be seduced by others. It's refreshing and thrilling to keep reading. Several of its characters are endearing and others reflect regions of the self that one wouldn't like to admit there exist. I will read the second delivery of the saga.”

Julián Trejos (CR)

Take notes at the start, it's complex.
Enjoy later, it's fascinating!

“I loved it! It's necessary a conscious reading during the first pages, then the mind soars with the next pages and I've suddenly found myself with that void of “it's over, I want more!” I'll start reading the second one at once. It would be a super hit if turned into a movie series.”

Jonathan Valembois (CR)

Magic, revenge, love, innocence, and loyalty

“A magical story that tells the dynamics among 5 races that could easily be compared to human evolution states. With characters innocent, loyal, compassionate who live with other ambitious, full of rancor. A good book to dive into the world of fantasy and to reflect on our realities and that which moves us from our hearts to keep on with our mission.”

Alejandra Reveles (CR)

A talented author immerses you into a new universe

“This novel is an oasis. Absolutely captivating. The characters' descriptions, the environments, their troubles, and perceptions are created step by step, masterfully. It's a novel that you can read and reread with delight and awe. Simply wonderful.”

Luis Alberto Ruiz (CR)

An original world, full of surprises. Complex and captivating plot

“There is a set of characters whose stories get intertwined masterfully. Characters very well defined and differentiated, full of light and shadows. The author reveals the universe that lies inside his mind in such a descriptive way that you can't help but to imagine the narrative as if it were a movie. The stories amalgamate in unexpected ways in a charming finale.”

Víctor M. Vital (MX)

A dynamic narrative of a wonderful world

“A thrilling story with adorable characters in a world full of surprises. As soon as I started to read, I fell in love with the first volume...”
