I discovered the Immortalis series after looking for something to read after finishing the Night Huntress Series by Jeanine Frost.
I picked up the Omnibus Edition and finished all three books in a day and a half. Without spoilers here are my pros and cons.
Pros:
1. Lysander, he reminds me of a mix between Bones and Jericho Z. Barrons.
2. Alyssa, she sweet and likeable, but does not kowtow under pressure and sticks to her guns.
3. The plot and the mythos of the creations of vampires and their lifestyle. Very original.
4. The supporting characters were all well developed and served a purpose.
Cons:
1. The cliffhanger ending at the finish of book three.
Overall, I have really enjoyed this series and am glad to see that book 4 will be out in a couple of weeks.
