I'm currently reading Mayan Mendacity by L.J.M. Owen. This book is the second in the Dr. Pimms, Intermillennial Sleuth Mystery series.
Dr. Pimms is back! Eagerly awaiting the return of her boyfriend, she gets a devastating surprise. Not one to dwell in her sorrows Elizabeth decides to work on the archaeological remains brought to her. This time she has a Mayan mystery to uncover.
