Following a grisly encounter with the Tiyanak, an evil creature from Philippine folklore, Janus Silang realizes that nothing in his life will ever be the same again. He and his family are now the targets of a powerful force that must be destroyed.

Janus and his friends escape to Kalibutan, where the Tiyanak cannot follow. There, he searches for Tala, the Tiyanak's goddess twin and the only being with the power to defeat it. This quest leads him again to the word of online gaming, where to his great dismay he discovers that he is not the only one seeking her!

The second volume in the Janus Silang series, Janus Silang and the Struggle for Kalibutan is adapted from the award-winning novel by Edgar Calabia Samar, one of Asia's best-known writers and multiple winner of the Philippine National Book Award.
