It's my book birthday! My middle grade scifi book, Mind Over Antimatter, is now out fully in print and ebook formats. I've learned so much about writing on this board, I just have to come back and say thank you.

Thirteen-year-old Cole Uribe can’t believe his luck when an invention contest wins him top security clearance. His mission: pose as the grandson of inventor Nicolás Araya and find Araya’s plans for a micro-black-hole-powered storage device—before Alzheimer’s erases Araya’s mind for good. Except…Cole’s not the only kid claiming to be Marcelo Araya. And one of them is telling the truth.
Can a real grandson, a fake grandson, a nosy neighbor girl, and the greatest mind ever to lose brain cells be a match for a top-secret, most ruthless organization?
