Welcome back to Mulberry Lane! In just three years, the life of sixty-two-year-old Louise had irrevocably changed. Diagnosed with early onset Alzheimer's, what the next three years would bring, remained to be seen. Kate's ex-husband has a new girlfriend. Under normal circumstances, that would have been fine for the twenty-eight-year-old Filipina. But there's a catch. He wants his new partner to play a bigger role in their son's life. Kate doesn't know how she feels about her only son having another mother. Sarah and Caleb are getting married. Their kids are thriving, and they are learning how to be better parents to Noah, who has ADHD. Life is perfect for the once widowed forty-four-year-old...until the day that it isn't.
