Tony Hawk's 900 Revolution: #13 Horizon

In this final book of the series, the surviving members of the Revolution reunite under the leadership of Zeke Grebes, Omar's long lost father. They're badly beaten, but together this NEW REVOLUTION team hopes to win back their stolen Fragments. However, the final piece won't come easy. Only an epic, skate-or-die battle will reunite the pieces and bring Tony Hawk's 900 skateboard and its power back together again.
