A Ruin, Great and Free (Blackstone) by Cadwell Turnbull is the third and final volume in the US Virgin Islands writer’s Convergence Saga, which began with No Gods, No Monsters and continued in We Are the Crisis. Set in a world where monsters of myth and legend reveal their existence to the world with calamitous results, the trilogy weaves a gripping story about secrets, belonging, and the ways we contend with the strangeness of others. As this final instalment opens, a secret community of monsters have found sanctuary from human persecution, but fear, hatred, and conflict loom. The parallels to the real world are clear, utterly up-to-the-minute, and raise the novel’s ethical stakes.
