Sequel to: A dark and hollow star.

While staying at the Seelie Summer palace with the infamous Queen of Light, half-fae Arlo is faced with a choice that won't only change the fate of the Mortal Realm forever but could condemn it to unimaginable cruelty.-- Novelist.

All Arlo wants is a quiet summer, but someone is still trying to summon the mythical Seven Deadly Sins. If this is the gods' attempt at returning to the Mortal Realm, it's Arlo they're going to use to do it. When Queen Riadne offers to host Arlo at the Seelie Summer palace, she hopes to see more of Vehan and Aurelian and perhaps even work out her complicated feelings for the gorgeous ex-Fury, Nausicaä. But no one trusts the infamous Queen of Light, and with the Summer Solstice approaching, everyone expects Riadne to finally challenge the High King for his crown. Soon Arlo is faced with a choice that won't only change the fate of the Mortal Realm forever but could condemn it to a cruelty the likes of which the Courts have never known. -- adapted from jacket
