My Sunshine Away by M.O. Walsh (2015)

syndetics-lc
Engaging novel about a man looking back at his youth and a traumatic event that occurred to his beloved neighbor girl, and how he became a suspect. 

Walsh does a gorgeous job of encapsulating what it's like to be a child and have limited information and also to look back as an adult and see what you missed. 

Lovely, lyrical (but not in love with itself) writing.
