The Sacrifice by Rin Chupeco
YA Horror - not my usual genre, which is why I love reading challenges, they get me out of the mystery aisle occasionally. Tales of a cursed island in the Philippines bring a television crew hoping to gather footage to produce a new reality show starring a famous ghost investigator who needs to rehabilitate his image. No one lives on the island, but the film crew needs a guide and they find a teenager, Alon. Alon is the only one willing to help them, but even they tell the crew that it would be best for everyone to leave. Most of the legends are true and people could end up hurt. Alon stays and helps, though, as they believe that's the best way for the most people to survive. Within minutes of their arrival, a giant sinkhole appears, revealing a giant balete tree with a mummified corpse entwined in its gnarled branches. And the crew start seeing strange visions.
