There now exists a London Calling Universe! What this means is all the books therein will be romcoms, have similar themes / vibes, and be set in the same world. Husband Material is a continuation of Luc & Oliver’s story and a direct sequel to Boyfriend Material, with Father Material concluding their arc. 10 Things That Never Happened is a standalone fake amnesia Christmassy romcom, and book 1 from the spin-off series Material World. (You get to meet one of the MCs, Jonathan, in Husband Material.) Material World book 2 will be Tyler’s book (he makes an appearance in Husband Material too) and has the unofficial title of Himbo de Bergerac. Which maybe gives you a clue as to what it’s about.
