A Distinguished Military Graduate, DMG, of West Texas State University, she was one of the first graduates of the United States Army Reserve Officer Training Corp two-year program, member of the military honor society, Scabbard and Blade, and retired as a Lieutenant Colonel from the USAR. She is a graduate of Monmouth University's MBA program and was featured in their Alumni magazine.

Heart of the Wolf received the 2008 Fall N.O.R. Reader Choice Awards for Best Paranormal Romance.

The urban fantasy series shows a contemporary world where humans who shape shift into wolves are so realistically portrayed, Publishers Weekly had this to say about Heart of the Wolf, "The vulpine couple's chemistry crackles off the page, but the real strength of the book lies in Spear's depiction of pack power dynamics, as well as in the details of human?wolf interaction. Her wolf world feels at once palpable and even plausible." And from Romantic Times, "A solidly crafted werewolf story, this tale centers on pack problems in a refreshingly straightforward way. The characters are well drawn and believable, which makes the contemporary plotline of this story of love and life among the lupus garou seem, well, realistic."

When interviewed, Spear talks about what influenced her to write such a realistic werewolf world: "For my wolf tales, Jack London’s Call of the Wild and White Fang helped influence my love of wolves and of their survival instincts, just like humans’ instincts to survive. I also was influenced by the way he told part of the story from the humans’ perspective and the wolves’. Ironically, I hadn’t read them since I was a teen, but only vaguely recalled this about his works as I began Heart of the Wolf. Yet they still influenced my desire to make the werewolf world as close to the real world as possible."
