[ria26]

i think its a mills and boon romance but i'm not sure, it starts off with a man looking for someone to settle some matter and he calls the residence but ends up talking to a redhead,he hears a crash and runs over to the apartment and finds a woman with a cast on her leg and a dog...i think she was a nurse who injured her leg while jogging in the park,it ends with him injuring his leg and she has to look after him..the cover is a woman in a green dress with red hair,the man holding her is in a tux and they are at a party or in a ballroom
