JOURNEY TO HART'S HALO is a near-future sci-fi adventure, set in 2033 on the world's first international space colony.

The project of eccentric technology billionaire Dr. Oliver Hart, Hart's Halo is about to be populated by Zero Colony. Space-crazy twelve-year-old Davey Randolph's dream is to win two of the twelve spots, for him and his mom, in a global lottery to spend five years aboard the Halo. Little does Davey know, but winning a spot in Zero Colony will only be the beginning of his life's greatest adventure

Constructed as a puzzle-propelled mystery, Davey needs the help of an international cast of clever and quirky pre-teens, and to conquer his own feelings of being an outsider, to solve the puzzles that will lead to a shocking discovery about the true fate of his missing father.

WENDY ORR, AUTHOR OF NIM'S ISLAND

A meticulously realized space adventure with an appealingly nerdy hero and a generous smattering of the puzzles he must solve to complete his quest!

Here's what some Tween Readers have said:

Hart's Halo, the book of books (13-year-old Jack) ?????

Reading this fantastic odyssey through the eye's (sic) of a child brings a new perspective to the world of science fiction. Through a gripping tale, the reader will experience not only a fantastic story but they may even learn a bit about higher physics and quantum mechanics. One of the best teen fictions I've read in a long time!

ARC Reader (12-year-old Domenic)

Lou Hood is now my second favorite author, after Rick Riordan!

JOURNEY TO HART'S HALO is great as a family read, too:

Engaging and imaginative (JenX) ?????

I wanted to try this book for my tween daughter ... I ended up reading Hart's Halo before I even gave it to my daughter, and just loved it! It ended up being passed around our entire household, and it was enjoyed by everyone (one really liked the setting and the storyline, another the puzzles and the scientific theories and ideas). I sent a hardcopy to my nephews, who live in another city, and we have now infected their family and friends with this book - I also like that there will be (hopefully) at least one more book coming up. Look forward to that!

Perfect for ages 11 - 14, especially 7th and 8th grades.
