Seven Echoes Saga: Echoes of the Solstice Istanbul is an open wound. A winter pact on the verge of shattering. A darkness threatening to devour everything. Surviving Prague was only the beginning. Now, Mikhail and Dimitri are dragged into the subterranean labyrinths of Constantinople by the echo of a myth humanity sugarcoated to keep from dying of fear: the legend of the Saint of Chains. Cornered by fierce new enemies, the brothers must forge unlikely alliances in the darkest corners of the city to stop a lethal force from rewriting an ancient contract. If they fail, not only will the promise of light on the longest night of the year be destroyed, but the very fabric of reality will be completely torn apart. But venturing into this hell comes at a price. In their desperate race to stop the end of the world, they will suffer an irreparable loss. Not everyone will make it out of the shadows alive, and someone they love deeply will not see the next dawn.
