While searching for poison ivy books at Alibris, my favorite online bookshop, I came across this terrific book by Cynthia Riggs, who has written a whole series of Martha’s Vineyard Mystery books.
But this one has an amazing cover showing a massive poison ivy infestation that plays a part in this story.
The book is greatly entertaining, weaving together a number of plots in interesting ways.
In the same way that the Spenser novels were favorites for Bostonians who would recognize the places, these books will delight anyone who has spent even a single vacation on the Vineyard.
Here is a link to this book at Alibris, but from here you can also find all of her books. And you can order from a whole list of indy bookstores.
