Grace

after betraying her best friend, Grace Ledger has ruined her own and her sister's chance at curing the illness the aliens brought when the god Loki attacked New York, and her only hope lies in finding a new cure that doesn't involve the horrors she saw in her and her friend's lab after they made a discovery.

one that could cure everyone plagued by the illness, and doom earth to a war with Asgard.

but when Nick Fury offers her another option, and brings up her family's dark doings, she finds herself thrown into the lion's den when she agrees to his terms,

and swears to defend the god of mischief, the one person she wants nothing to do with.
