From the World of Percy Jackson: The Court of the Dead

A BRAND-NEW ADVENTURE FROM THE WORLD OF PERCY JACKSON AND THE OLYMPIANS From #1 best-selling author Rick Riordan and award-winning author Mark Oshiro comes a new adventure featuring two of the most popular characters from the world of Percy Jackson and the Olympians. It´s been three months since demigod boyfriends Nico di Angelo and Will Solace returned from Tartarus, and there hasn´t been a single quest for them in all that time. So, when Nico´s half sister Hazel asks them to come to Camp Jupiter to help with an ´issue´, Nico shadow-jumps at the chance to do something. What Hazel didn´t tell the boys is that she´s providing a haven for a group of monsters who´ve escaped the Underworld! Apparently, during Nico and Will´s trip to the Underworld, they showed the monsters that they don´t have to be evil - that the monsters have options. But then the monsters start disappearing from the camp and it´s clear a dark force is at work - and Nico, Will and Hazel are shocked to find that they´re connected to it . . .
