Land Meets Sea. Men meets Dolphins, #3

Where Land Enhanced military soldiers meet Sea Enhanced Life, this is the last of the 3 Volume set. That describes in Volume 1 Dolphins Enhanced for Military use, Volume 2 Solders Enhanced for weapons, and now Volume 3 the Dolphins seeks out help and offer training to the Enhanced Solders. The Training was to advance the Soldiers to be better and stronger than they were while asking the soldiers to help rescue other sea creatures like themselves that are in land-based research military labs.
The story takes an interesting twist as the teaching of the enhanced soldiers begins the use of the ancient underwater transport system and the great changes the new joint land and sea team are affecting the earth. Volume 1 & Volume 2 can be read as separate books, but to read Volume 3, both 1 & 2 should be read first.
