In the quiet hills of rural Wales, two teenage girls are separated by a century. When 14-year-old Amy arrives at a secluded farmhouse with her family for the spring holidays, she carries a silent weight -- the unresolved grief of losing her best friend, Suzy. But in the stillness of spring and the silence of the hills, she discovers something unexpected: a faded name on an old bedroom wall, a notebook tucked away, and a story long forgotten. What begins as a curious mystery soon draws Amy into a hidden past that speaks straight to her aching heart. Through old letters and a weathered notebook, Amy uncovers the story of Sarah, a spirited young girl swept up in a local 1922 revival -- a powerful spiritual movement that transformed lives and divided communities. ​​As Amy reads Sarah's words and walks the same paths she did, the past begins to speak into her present. Grief, guilt and silence begin to shift. And maybe, just maybe, healing can bloom where sorrow once grew. Mystery in Spring by Eleanor Watkins is a young adult mystery for girls about friendship, faith and the unseen connections that bind us across time.
