And one more PPP ^^^
I very much enjoyed Joanne Dobson's Karen Pelletier books back when I was reading them mostly during graduate school - the academic background seemed quite appropriate. Now the fifth book in the series,
The Maltese Manuscript, is on sale for $1.99 in the US, and discountable at Kobo US.
