The last part (1/4) just gives a detailed background on Hazel and Leo's lives and early relationship (it's also when they first meet), and while it is not mandatory, it is highly recommended.
Hazel Whitacre is an 18 year old biracial girl from Brooklyn. Leo Chamberwell is an 18 year old white boy from London. Hazel is renowned in America for her intelligence, as she became a bestselling author and student at Columbia University at the age of 16. Leo Chamberwell is renowned in England, because his father owns the world's most successful bank chain, and he is in line to inherit it. Together, their love finds a way, despite Leo's father's hatred for Hazel and all that she is and the distance between them.
