Are there any fiction books about someone who committed suicide and can see how people react to his death from the afterlife?

I agree with Mortal Instruments Series by Cassandra Clare (I also love the Infernal devices by the same author) The Percy Jackson series by Rick Riordan is great as well, if you want humour adventure and myths (doesn't matter if you hated the movies or not) Graceling, Fire, Bitterblue by Kristin Cashore; very intriguing fantasy based plot for all three. Shiver Series by Maggie Stiefvater; it doesn't even matter if you hate werewolves, these books are WAY different to the typical 'Alpha is my boyfriend' junk, and extremely good. Awakening by Natalie King; paranormal plotline but still relatable to teenage girls.

The Cat Royal Series, I just really loved these books and all the characters but I can't remember the author. Hope this helped :3.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
