A monster is on the rampage, a bond of trust is shattered and headless corpses turn up on the streets of Baltimore.. It has been two months since Sarah defeated the Dark, and she just wants everything to return to normal and enjoy her last year of High School. Normal though, is not the life of a Tether Keeper: even one as reluctant as Sarah.. Persuaded by CT to help in an investigation that shatters their friendship. Sarah once again finds herself alone and completely out of her depth. Lulled by the seemingly benign leadership of the Vigilie, she turns to the Custodiet for help. Meanwhile, a creature of the night long thought extinct comes to Baltimore, and rumors of vampires fill the city with fear as the streets wash with blood. Except One, the second book in the Tether Saga by Nick Davis and Katrina Roets continues the adventures of Sarah Taylor as she tries to survive a perilous dark supernatural world, that exists just in the shadows of our own.
