The Love of My Afterlife by Kirsty Greenwood

Girl chokes on a hamburger. Girl wakes up in limbo in the "afterlife" with a dreamy stranger. Turns out guy is there by mistake. Girl gets one chance to go back to Earth to find said hunk and live her best life.

Funny, clever, smart and sweet banter ensues. This was a fun one, with a little (genuinely surprising) twist at the end.
