Mostly good, a couple of duds.
Under the floorboards: bland artwork and predictable plot.
Spring cleaning: cute and absurd; bonus points for humour.
The keeper's treasure: solid artwork and story but a troubling resolution imo.
The butter thief: nice art, clever enough plot.
The soldier's daughter: preachy and lacklustre plot.
Whatzit: engaging cartoony art, loved the resolution.
The escape option: well-plotted with lovely illustrations, deserves to be read twice.
