I loved this mystery. It hooked me from the beginning with the plot, and then as I got to know the characters I was way more interested in them than the treasure hunt. Great for fans of When You Reach Me or All the Greys on Greene Street. ( )

This book was not for me. I thought the plot sounded interesting, but it smoldered and winked out. Two new kids in Dobbs Ferry are neighbors: one from a loving Indian family, and one running from the 'hood, missing his brother. With graffiti and a search for smuggled diamonds in the background and a gang seeking retribution, the plotlines were either contrived, convoluted or both. While I got the connection between the two kids, which seemed sensible, the rest of the relationships in the book were weird, strained, or preposterous. My advice is to skip this one. ( )

This multifaceted mystery has plenty to offer. There's the big-city vibe of New York, parkour, and graffiti tagging; the lure of illicit doings at night; a search for missing diamonds. The local history of the aqueduct even weaves itself into the mystery. And the background stories of the main characters adds dimension: Myla who never gets noticed decides to delve into the mystery of the diamonds, and the tension between brothers Peter and Randall whose father died under mysterious circumstances. Young readers will identify with relatable Myla and Peter and the pace will keep the pages turning. ( )
