A blackberry winter is a snowstorm well into spring. Claire is assigned to do a story for Seattle Herald where she is a reporter on a storm in May that occurs on the exact day as it did in 1933. She flounders for awhile until she finds the storyline she has been looking for, the mysterious disappearance of a three year old boy during the storm of 1933. The book alternates between present day and 1933, and through this alternation, we learn about Vera and the ties that bind us all. I've read many of Sarah Jio's books, but I think I have enjoyed this one the most.
