Skulduggery Pleasant: Mortal Coil

Valkyrie Cain is the main female character in this story and she is a strong and capable character. She started out weaker and more vulnerable in book 1 but she has worker her way up the ladder and now she has quite a reputation for foiling plans and wreaking havoc. She has become one of the most feared mages and she has recently found out that she is going to be the one to destroy the world and kill everyone. She is Darquesse the girl that has been in all the visions of the future. She doesn't want this to happen though and she fears that someone will find out her true name and use it against her. She decides to act independently and not tell Skulduggery (her detective partner) as she is worried he will judge her by it and try to kill her. So she has recently gone to seal her name alone and put her life on the line for the people she loves. She literally dies and comes back to life to have her name sealed and is confident now that she has changed the future so she doesn't destroy the world. Valkyrie is a true warrior she has fought many times and is brave and courageous. She is also very intelligent and strong being able to cope and pull through the most difficult situations. She does have a boyfriend called Fletcher but she does not let Fletcher take over her life. She still likes to think of herself as an independent and capable girl.
