Cursed Moon by Jaye Wells - This is the second Prospero's War
Novel that I have listened to. I love the characters. Kate Prospero is a great strong female character who has demons of her own to overcome. She is supported with a great team of Magic Enforcement colleagues. Add a past love to the mix and the tension and danger just keep ramping up. A fun book to listen to or to read.
A Call to Duty (Book 1 of Maniticore Ascendant) by David
Weber and Timothy Zahn - A interesting story about how Manticore came to be the power they are in the Honor Harrington series. This can be an introduction to both series but I really think fans of the Harrington series will be the main audience.
