Foster care -- fiction
Why red roses on Valentine’s Day? The language of flowers was invented for communication between lovers—a flower can send a coded message. Red roses represent passionate, romantic love. Pink roses are sent for friendship. Shakespeare uses the language of flowers when Ophelia gives Hamlet rosemary for remembrance before she ends her life.
Victoria Jones, in The Language of Flowers, by Vanessa Diffenbaugh, is obsessed with the subject, but she uses it to spread animosity. Having aged out of the foster care system in California and facing imminent homelessness, her life reads like a series of unfortunate events.
