5 Star Readers' Favorite medal winning book! Here's what the Readers' Favorite critics are saying:

"From the beginning to the end, the story grabbed hold of me and did not let it go. I connected with the story and the style of writing right from the start. The way the story was told, how it grew, how it developed, and how the authors differentiated between the people of different planets made the story more enjoyable. This is a fast-paced, witty, humorous and action packed story that I thoroughly enjoyed. Definitely one of the best sci-fi and young adult novels I have read this year."

"This is a phenomenal book with strong, distinctive characters put in a situation that tests them in many ways. The conflict is strong and it is introduced right off the bat and in a way that grabs the attention of the reader instantly. It is interesting to watch the characters as they evolve through the conflict to a satisfying climax. I loved the great writing, the gripping plot and, above all, the wonderful characters. Unlock the Unknown: New Earth will certainly be a delightful read for fans of young adult fantasy."

"Secrets drive the plot as each of them has a secret they don't want uncovered. A lot of sympathy goes out to the group for they're all struggling in one way or another, but a possibility of friendship may be what saves them all. Sabrina Estafo and Michael Estafo bring a fun perspective and excitement to the science fiction genre, with worlds rich in details, jargon, history, and culture. Unlock the Unknown: New Earth is an exciting start to a series; clever and funny, dangerous and action-packed."

"Unlock the Unknown: New Earth is a must for lovers of science fiction and fantasy, and at the end of this book the real journey is just about to begin. From all that occurs, I can confidently say that it certainly shows a lot of promise as a series. I also liked the addition of the rather comprehensive appendix of terminology and character biographies at the end of the book. I really thought they added a little something special. A gripping read, full of surprises. I look forward to reading more work from Michael Estafo and Sabrina Estafo in the future."

"The narration is vivid and detailed and the author makes the characters tangible and the scenes come alive for readers. The journey of discovery undertaken by the four and their understanding of the planet New Earth is fascinating as the story unfolds, and it will keep readers glued to the book till the very end."
