One of the best male characters out there has to be Rhysand from Sarah J. Maas's A Court of Thorns and Roses He's adoring, caring, sweet, protective but still willing to let those around them make their own choices, etc. He's also powerful, and will do anything to protect those he loves.
(Yes, Sarah J. Maas appears on this challenge again. What can I say? I love her and all her works.)
William Owen Herondale from the Infernal Devices Trilogy by Cassandra Clare. He's sassy, sarcastic, witty, and absolutely hilarious. What can I say? I guess I have a weakness for those characters with a hard exterior and the cliched heart of gold inside. Also he loves reading and poetry, who doesn't love that?
