Midnight society

"In one terrible moment, England's greatest adventurers cast aside their friendship, making a choice that would come to haunt humanity. Forty years later, secret agent Matilda Finn is called to help England's most mysterious intelligence group, MI: Omega, and is sent on a desperate rescue operation to Scotland's Loch Ness. Underneath the black lake, Matilda will face the cosequences of that decision made so many years ago and question her already loose ties to human society."--Page 4 of cover.
