Good Riddance (PB) by Elinor Lipman

In a delightful new romantic comedy from Elinor Lipman, one woman’s trash becomes another woman’s treasure, with deliriously entertaining results.

Daphne Maritch doesn't quite know what to make of the heavily annotated high school yearbook she inherits from her mother, who held this relic dear. Too dear. The late June Winter Maritch was the teacher to whom the class of '68 had dedicated its yearbook, and in turn she went on to attend every reunion, scribbling notes and observations after each one—not always charitably—and noting who overstepped boundaries of many kinds.
