From the World of Percy Jackson: The Court of the Dead (A Nico di Angelo Adventure)

冥界歸來後，Nico與Will應邀前往Camp Jupiter協助Hazel解決一場微妙又棘手的局勢——有怪物開始尋求庇護，想在此展開新生活。但好景不長，營地中的怪物陸續失蹤，一場針對他們的報復行動悄然展開。在這場冒險中，熟悉的角色再次登場，挑戰的不只是身體極限，更是對過去與自我認同的直視。Rick Riordan與Mark Oshiro以充滿想像力的筆法，帶領讀者重新思考「誰是怪物？誰是英雄？」的界線。

New York Times #1 best-selling authors Rick Riordan and Mark Oshiro collaborate again on a new adventure in which Nico di Angelo teams up with his half-sister Hazel Levesque to protect . . . monsters?

A few months after returning from the depths of Tartarus, demigods Nico di Angelo and Will Solace agree to join Nico's half-sister Hazel Levesque at Camp Jupiter on the West Coast. She needs their help in managing a situation that the boys inadvertently brought about: the demigods showed the monsters of the Underworld that they have options; they don’t have to be evil. 

Now some of those monsters have taken up residence at Camp Jupiter to seek refuge. Nico and Will are on site assisting Hazel when one by one monsters start disappearing from camp. A mysterious dark force is at work, and its plan is to punish all monsters for their past crimes. 

Things only get worse when Nico, Will, and Hazel learn that they’re all connected to it . . .

In this brilliantly inventive and laugh-filled adventure, the best-selling team of Rick Riordan and Mark Oshiro manipulate the Mist to make readers see things in a whole new light.
