Interesting.... mildly creepy... and kind of weird.
And apparently based on a story Avi was told by a kid he met.... so it's a "true" story... maybe.
Boy meets ghost, ghost takes boy back in time, boy must solve ghost's murder.
Probably would appeal to late elem./middle school boys, I would think. Especially ones that like mystery and history.
Set in Rhode Island, so New Englanders might get more out of it than us Westerners, lol.
