Who is Rebecca Baxter from Only the Good Spy Young and what is their importance?

Rebecca Baxter is Cammie`s best friend and a fellow student at the Gallagher Academy. Fearless, assertive, aggressive, and proudly loyal to Cammie, she is Cammie`s staunchest and most secure ally, someone whose identity and loyalty is never in question. She is a manifestation of several of the narrative's key themes and a positive example of loyalty, friendship, and identity against which Cammie, and the reader, can measure all the other uncertain friendships and identities around her. Rebecca is also a thematically contrasting character in another way - where Cammie is essentially trapped by her circumstances, Rebecca is quite free, a circumstance to which Cammie, somewhat enviously, aspires.
