Penderwicks on Gull Cape

This year, the Penderwick sisters are going on summer vacation for the first time together, without their eldest, Rosalind. But Geoffrey, the “honorary brother” of the Penderwick sisters, will go with them. This means that Skye will have to become... the “oldest”, that is, take responsibility for her two younger sisters. And everything would be wonderful - a cozy house by the sea, salty spray and cheeky seagulls, but the sisters can drown, burn at the stake, go crazy or even burst without the supervision of Rosalind and dad!
Will Skye learn not to be afraid and take responsibility? Will Jane's life change after meeting Dominic, a young guest at the Seagull Hotel? Is it true that Betty has an absolute ear for music? And most importantly, will Geoffrey be able to maintain peace between the sisters?
For middle school age.
