The Day We Ate Grandad - Pagham-on-Sea

Three possible futures. Two versions of the apocalypse. One chance to save the world. Wes Porter, a severely depressed insanity-inducing playboy, is detoxing from hallucinogens that have unlocked his ability to see versions of potential futures - and he's just foreseen two ways the world could end. Normally, Wes would leave the hero bullshit to somebody else, but he can't abdicate responsibility this time...
not when both those apocalypses might be his fault. With some prompting from a mythological bard-prophet who may or may not be real, and a lot of assistance from his monster-eating baby sister who desperately wants to move out of his apartment, and their soothsayer cousin who has his own demons to fight, Wes attempts to save [his] world... but have his poor decisions doomed them all?THE DAY WE ATE GRANDAD is the third book in the Pagham-on-Sea series.
It is a dysfunctional family cosmic horror novel for fans of WHAT WE DO IN THE SHADOWS, THE MAGNUS ARCHIVES, and THE CALL OF CTHULHU, with themes of bereavement and grief, generational trauma, and a dash of Roman/Welsh mythology.
