The Care and Handling of Roses with Thorns - Margaret Dilloway (2012)
Cal is a high school science teacher who is busy at school and busy at home. As a breeder of new and unusual roses, she has to juggle that with kidney failure and having dialysis every second day.
Just as things are are settling into a pattern, enter the teenage angst as her niece appears to stay with her, while her sister goes to work in Hong Kong.
For me it was ok, I liked that Cal was a bit prickly like her roses, but I felt like it was a story that I had heard before.
