The Walls of Westernfort by Jane Fletcher

All Natasha Ionadis wants is to serve the Goddess as a Temple Guard, and she volunteers eagerly for a dangerous mission to infiltrate a band of renegade warriors and imprinters. One of three temple guards sent to infiltrate Westernfort and assassinate the rebel leaders, Natasha accepts that she will likely die in the process.

But, once away from the temple, the issues are no longer so simple and she must revaluate her allegiances and her beliefs. Living undercover alongside the women she has sworn to kill, Natasha discovers friendship and, with one woman in particular, something far more.

Is it already too late to discover what she really wants from life?
