A Shore Thing by Joanna Lowell
For a trans, historical beach read, pick up A Shore Thing. Double bonus points for the beachy cover and title. This takes place on the seaside of Cornwall, where Kit is starting a new life after leaving behind his old identity as a painter in the Sisterhood of women artists. Muriel is a botanist trying to commission Kit for seaweed illustrations. Kit reluctantly agrees, but only if the two of them prove to the local all-male cycling club that they should start allowing women in. As they cycle together, they begin to fall for each other.
