Who – or what – is watching Lexi? Friendly Angel or deadly foe? Conall is incensed to discover Lexi is under surveillance; especially since his precious sister is pregnant with twins; fathered by ex-angel Michael. With Zach, Alex, Vlad and the rest of the squad on a mission so ghastly it will leave Alex shaken and disgusted, it is left to Conall to track down this potential threat. What he discovers shocks him to the core, but before he can take action, the unthinkable happens: Lexi is taken. Can ex-angel Michael find his mate in time? Will Lexi and her unborn twins survive? Find out in this, the last instalment, of the Defender's Blood series.
