Wildest Dreams (Thunder Point #9)
Robyn Carr

Lin Su Simmons and her teenage son, Charlie, are fixtures at Winnie Banks' house as Lin Su nurses Winnie through the realities of ALS. A single mother, Lin Su is proud of taking charge and never showing weakness. But she has her hands full coping with a job, debt and Charlie's health issues. And Charlie is asking questions about his family history—questions she doesn't want to answer.
When Charlie enlists Blake's help to escape his overprotective mother, Lin Su resents the interference in her life. But Blake is certain he can break through her barriers and be the man she and Charlie need. When faced with a terrible situation, Blake comes to the rescue, and Lin Su realizes he just might be the man of her dreams. Together, they recognize that family is who you choose it to be.
