Bea is sick and tired of her brother Guille breaking her toys. For her birthday, she asks for a big bike that he won't be able to use. The only problem with it is that she is scared to try it out and afraid he might learn to ride it before her. Readers will not believe the lengths she goes to in order to keep the bike away from Guille.Bea tiene seis años, un hermano pequeño y mucho caracter. A lo mejor el carácter lo tiene por culpa del hermano pequeño. Desde que él apareció, Bea es un torbellino de sensaciones.
