They got CLOSER!
"Fans are going to have a hard time putting it down. There is a lot of action; lively dialogue; diabolical villains and feisty teens; clever cat-like companion hunters; things that blow up; torture and mind-manipulation; family and friends in danger; and trust and betrayal. A great science-fiction adventure series for boys, and girls will enjoy it as well." -- VOYA*
"Gordon and Williams move plotlines around like two generals directing a simulated battle. The authors have created quite a world." -- Booklist
They fell for FREEFALL!
“Gordon and Williams are one of the world's hottest writing teams.”

“Propelled by chases, attacks, explosions, cunning deceptions, and acts of heroism and stupid bravado.”
