Ripple

Ripple is one of the most original novels I ever read, the tale of dolphins living 20,000,000 years ago on the planet Azure (Earth), and their advanced culture and society. Written by New Zealander Tui Allen, this self-published work has attracted considerable attention and stands a good chance of really taking off. It's available from Amazon.

My cover is a digital piece depicting the title character and her ultramarine friend Cosmo (it seems that the dolphins of the distant past came in rainbow colors).
