In this book Professor Snape makes a vow to protect and assist Draco Malfoy, Harry gets a Potions book that used to belong to the Half-Blood Prince and therefore has a bunch of helpful notes. Harry finds out about the Horcruxes that need to be destroyed in order to kill Voldermort. Him and Professor Dumbledore leave the school in order to fetch and destroy one of these Horcruxes which is Slytherin's locket. They bring it back to Hogwarts but Dumbledore is weakened from drinking a potion that helped Harry get the locket and then... Dumbledore is killed by Snape who didn't really give Draco a chance to do it, then he tells Harry that he was the Half-Blood Prince and disappears before Harry can do him any harm. Harry decides to not return to Hogwarts for his 7th year, he will instead dedicate his time to finding the Horcruxes and therefore killing Voldermort.
For this mani I did the potions book on my index - an erlenmyer flask with bubbles and little 'scribbles' on each side left by the Half-Blood Prince. Slytherin's locket is on my middle finger, then the killing curse on my ring and pinkie that Professor Snape used to kill Dumbledore. Sniff. I cried so much when he died :(
Don't forget to leave the other ladies some love as well :)
