Seven Wonders Book 3: The Tomb of Shadows

Teamwork, bravery, and believing in yourself are overlying messages in the first two Seven Wonders books and in The Tomb of Shadows, as well. Here the characters struggle less with whom to trust; they know what side they're on.

Three bombings at different points in the book send the main characters flying, giving them minor injuries. They're also cut by sharp griffin talons, gassed, shot at, chased by a raging fire, concussed in a crashing plane, and attacked by zombies whose body parts go flying (with more typical zombie imagery of eyeballs coming out of sockets and skin flaking off to the bone, etc.). Each of the three suffers seizures and requires what's just called "treatments" to prolong their lives -- with their special genetic mutation, no one lives past the age of 14. There's a sad death of a monkey who was protecting Jack and the loss of a mentor figure who sacrifices himself to the cause. There's talk of sad losses of parents and missing parents; Jack remembers the day he received the phone call about his mother's disappearance and presumed death. A whole base is attacked with people beaten and held prisoner. Some gunfights and fistfights.

"Flipping" said once, and a mention that a truck driver has a "potty mouth."
