Frick slowly ratchets up the suspense ... I’m not sure Frick adheres fully to the rigorous logic of Sliding Doors, in which each decision leads inexorably to the next event, but it’s great fun to watch her two narratives collide and diverge.
Frick keeps readers deliriously off-balance, tossing out just enough breadcrumbs to make the truth seem obvious only in hindsight. The format gives new life to the unreliable narrator trope, and Frick is excellent at establishing a plausibly lived-in dynamic between Jane and Esme.
Frick skillfully builds details into one plot that morph into something shockingly different in the other. The prose is streamlined, the pace headlong, and the surprises satisfying on both sides of reality.
