The Titan's Legacy (3 Book Series) by J.J. Thompson (epub) [BluA]

Summary:
"Remember the Titans." Three enigmatic words received in an anonymous email that will change fourteen year old Justin McLeod's life forever.

Smaller and slighter than the other teens in grade nine, Justin is the perfect target for bullies. But their taunts and abuse don't bother him, because he has a secret. After an accident at the age of twelve left him unharmed, Justin realized that he had become almost totally immune to physical pain and damage.

Now he wants to stand up for himself, prove that he isn't afraid. But his mother won't hear of it. She fears that if his unique gift is discovered, the government would take him away from her and use him for their own purposes. He thinks that she's just being paranoid.

And then Justin receives that mysterious email. 'Remember the Titans'? What does it mean? He's intrigued enough to research these Titans online. Once that resource is exhausted, he heads for the local library. And there things take a turn for the worse.

Justin is confronted by a menacing group of brown-suited men who follow him home. Terrified, he finds himself trapped in his apartment with his mother and the custodian, Mr. Wilson. And when the strangers begin battering down the front door, Wilson offers Justin his one chance to escape to safety...using his own bathtub.
