These books are incredibly short and repeat themselves a lot. They should have edited out some of the repetition when they made them into these collections.

Despite Tyson’s young age, he has solved more mysteries than most people his age or older, to solving the mysteries of the dome losing oxygen and the aliens in the boxes. But when they discover a comet is heading right toward Mars, there is nothing they can do but get their best young man, Tyce, to help stop the comet in time.

I like tyce because he is the definition amazing. He is like a super human in a wheelchair.

This story is based on mars, there are some slow parts to the book but when it picks up the pace it starts going really fast. It is a bit confusing on how fast pace the is of the story goes it is almost like there is a new idea every second page. In the books you get really attached to two characters tyce, and ashley. They are just characters you would want to meet in real life.

This book has a lot of the same problems we have in our society, from lying to testing things that would blow the world up like the hammerhead.

I would suggest this book to a lot of people because there is a little bit of everything you would enjoy.

Tyce has solved many mysteries, like what was depriving his station on Mars of oxygen, or that some strange creatures he found in a greenhouse were not aliens, but the result of genetic engineering. But now some of the biggest mysteries lie in wait, with Tyce being the only one who can solve them. These mysteries include: why and how did these black boxes mysteriously appear when no man had ever placed them there? How did the former director regain control of the dome? And why does his new and only friend his age seem to be hiding something?
