From the back of the book:
ARE YOU CLEARED FOR THIS?
For eighty years, your ouganization has fought to protect huumanity by unearthing evils older than the world. You violated every law to save people who'll never know you exist. You took down fanatics who worshipped horror itself.You dug up truths that all the powers of government and magic tried to conceal.
You're about to wish you'd left well enough alone.
