When Nell's Aunt Loulou passes away, Nell heads to the Quincy estate in Cleveland from her home in Oregon. Nell's mother (now deceased) and father moved out west years ago, because they found being around the wealthy Quincy family too stifling. At the reading of the will, Nell is named executor of the estate and is bequeathed a necklace that is unaccounted for. Then, in cleaning out Loulou's bedroom, Nell finds a necklace containing a giant sapphire with nine other jewels. Feeling that this is the necklace mentioned in the will, Nell goes about finding out its history, but other family members attempt to control what happens to it.
Told in alternating chapters, the reader follows the contemporary story of Nell and her relatives, along with the 1920s tale of brothers Ethan and Ambrose Quincy and the woman they both loved, May. The Necklace by Claire McMillan is an engaging story filled with details of old wealth and of times gone by. Give to readers who enjoy Lauren Willig's standalone novels.
