The Military K-9 Unit brings the K-9 series onto military bases. All eleven books were published in 2018, from Tracking Danger and Mission to Protect through to Valiant Defender.
Bound by Duty, Top Secret Target, and Explosive Force raise the military stakes, while Standing Fast and Battle Tested show the personal costs of the dangerous work. The Military K-9 Unit Christmas anthology caps the series. The military setting adds chain-of-command dynamics and base security concerns to the romantic suspense framework.
