Your heroine is on crutches.
Why? How did she get injured or is she injured?
Maybe she’s faking it to get out of doing something she doesn’t want to do. Maybe her boyfriend planned a hiking vacation, and she faked an injury because she doesn’t want to go. Maybe he drags her along anyway. She hangs out in the lodge and meets someone new.
Or maybe a handsome stranger bumped into her, and she fell and sprained her ankle. He feels obligated to help her – because he’s such a nice guy – and the two fall in love. (She could stay on the crutches just a little bit longer because she wants him to hang around.)
Or maybe your heroine is clumsy on her crutches, and she falls into a handsome stranger.
So many paths you can take with this simple story starter!
Have fun and happy writing!
