Metatron: Dagger of Mortality by Laurence St. John
Are superheroes immortal, or can they die?
Tyler Thompson has been in isolation for the past eight months, mastering his superhero training. On graduation day, Tyler is urgently summoned, and now he must confront a new evil.
When Kelltie, a female scientist from Steele Corp, threatens Tyler's destiny by framing him for the largest mass killings in American history, there’s nothing he can do to stop it. Making matters worse, Kelltie collaborates with Black Shadow, who has his own agenda—to use the Dagger of Mortality and kill Metatron.
Feeling vulnerable, Tyler finds inspiration from Master Dogmai, and now he must render the most arduous decision of his life. He can either save himself and his beloved girlfriend, Kendall, or he can save millions of helpless people—and hinder Kelltie's plan.
