DEEP ROOTS by Ruthanna Emrys

A new review over at Tor.com:

Winter Tide, Ruthanna Emrys’s accomplished and astonishing debut novel, was an intense and intimate subversion of the Lovecraftian mythos, told from the point of view of Aphra Marsh, the eldest of two survivors of the United States’ genocide of Innsmouth. In Winter Tide, Aphra made reluctant common cause with FBI agent Ron Spector (though not with his suspicious colleagues) and accidentally accreted a family around her. Winter Tide is a novel about the importance of kindness in the face of an indifferent universe, and I love it beyond reason.

I may love Deep Roots even more.
