3. The Fault in Our Stars
Why cry: it's no secret that both main characters, Augustus and Hazel, are suffering from cancer, though they're both currently in remission.
This is a realistic portrayal of young love, made more bittersweet with their illnesses (and the crazed author of their favorite book).
You'll need them.
This is a great matching necklace to get you and your partner for Valentine's day!
