Clementine Rose and the Pet Day Disaster (Clementine Rose #2) by Jacqueline Harvey

CLEMENTINE ROSE
is so excited! She's going
to start school with her best friends
Sophie and Poppy and she can't wait.
But when she gets there, instead of
the lovely Miss Critchley, her teacher is the
much sterner and shoutier Mrs Bottomley.
And then there's Angus, a little boy who
delights in tormenting her from the
moment they first meet.

After her first day, Clementine decides
school may not be so much fun after all.
But the announcement of a Pet Day
changes everything. If Lavender
the teacup pig can come to
school with Clementine,
everything will be all right
. . . wont't it?
