Tristan Strong Destroys the World (Tristan Strong, #2)

Tristan Strong, just back from a victorious but exhausting adventure in Alke, the land of African American folk heroes and African gods, is suffering from PTSD. But there's no rest for the weary when his grandmother is abducted by a mysterious villain out for revenge. Tristan must return to Alke--and reunite with his loud-mouthed sidekick, Gum Baby--in order to rescue Nana and stop the culprit from creating further devastation. Anansi, now a "web developer" in Tristan's phone, is close at hand to offer advice, and several new folk heroes will aid Tristan in his quest, but he will only succeed if he can figure out a way to sew broken souls back together.
