Natasza Waters has a great beginning in these first two books. The Code Name series features a US Navy SEAL team and the heroine in both books is a Canadian intelligence expert hired to work at the base. Ms. Waters is working on the next book, Code Name: Nina's Choice which will tell the story of Nina and Mace. Mace quickly became a favorite character in Code Name: Ghost and Nina was introduced in Code Name: Kayla's Fire. I haven't seen a publication date yet but you can be sure I'll be keeping my eye out for this one.
