I continue to find MaryEllen one of the less interesting historical characters, and maybe that's because her stakes are relatively low (which is ok; these characters are 10 year olds and history shouldn't necessarily be a gallery of trauma). The Finders Keepers Rule revels in it's Daytona Beach setting, and would be good for learning about the Atlantic coast of Florida, and who actually owns something that's found via salvage.

Only one of her friends was around (a little surprised the Karens weren't interested in prepping for the big dance?) but there were lots of good interactions between the Larkin siblings. ( )
