Fear Death By Water, by Emily Cook

Second paragraph of third chapter:

Thankfully, her bedroom was on the third floor of Longstone Lighthouse. Flooding had been an unfortunately frequent occurrence in her downstairs bedroom at their old lighthouse on Brownsman Island. The windows often failed to withstand storms, meaning large waves would cascade through the broken frames and shattered glass. On one occasion, when she was a young girl, Grace came close to drowning as the room filled with seawater and forced the door shut. The memory of it still sent shivers down her spine with every subsequent storm that passed.

The first original Fifteenth Doctor novel, by Emily Cook, who organised the memorable Twitter watchalongs during lockdown in 2020. Set between the two Fifteenth Doctor seasons, it’s a straightforward aliens-intervene-in-celebrity-history story, the celebrity being lighthouse heroine Grace Darling (apparently a relative of Cook’s; Cook writes herself into the book as well) and the aliens turning out to have some complexity. Gorgeous characterisation of Ncuti’s Doctor, not massively original plot. You can get it here.
