An Indecent Invitation was my first book by Laura Trentham but won't be my last. Ms Trentham has delivered a well written book. Gray and Lily's story is peppered with awesome characters, suspense, action and sexy bits. I enjoyed An Indecent Invitation and look forward to my next read by Laura Trentham. An Indecent Invitation is book 1 of the Spies and Lovers Series but can be read as a standalone. This is a complete book, not a cliff-hanger.
