Amaurosis

In a world where supernatural entities roam freely, there are 'Hunters' who eliminate the more dangerous ones. Seers are individuals blessed with some remarkable ability but are born blind (Amaurotic blindness is a marker for the Seers, in this world.). Most families have their ""seer"" children taken away at birth by the government. A few families avoid having their children born in the hospital and if they have a ""seer"" baby they try to hide them. The government raises the children to use their abilities and matches them up with Hunters to assist them in eliminating the malevolent supernatural… Sadly, since most hunters become so after suffering from some personal tragedy, they are rarely known for their compassion. Seers tend to have a short life span; being mistreated, or used as bait or just getting killed by the thing that their Hunter are hunting.
James was lucky to escape being taken by the government at birth and then managed to stay off-grid. Once an adult, he managed to get in with an underground organization that helped Seers from being caught.
Dean is a Hunter who has recently lost his Seer and requires a replacement urgently, but he doesn't have the time or energy to deal with the Government. Instead, he has a contact who works with an organization that hides seers and strikes a deal to obtain one.
