Publisher's summary
4.1 Call to Arms by Matt Fitton

Mike Yates braves a stormy night in the Lakes to help celebrate a milestone for John Benton. An evening of fond reminiscences of old glories and friends awaits. But a long-buried past is about to catch up with them.

Meanwhile, on the rain-lashed moors, what begins as a routine mission for modern-day UNIT quickly becomes a fight for survival.

4.2 Tidal Wave by Guy Adams

When an experimental tidal power generator needs its eco-friendly credentials checked, Kate Stewart calls in an expert.

Soon, Jo Jones is bound for 'Project Charybdis' in the South Atlantic, along with an awestruck Osgood.

But out at sea, a treacherous plan is set in motion to awake an ancient race. Beneath the seabed an army is sleeping - an army of Sea Devils!

4.3 Retrieval by Guy Adams

As the Earth's primeval rulers reclaim their birthright, UNIT must stand against them. Kate Stewart and Osgood venture into a Mediterranean stronghold to retrieve a means to fight back.

But a Silurian warrior is on their trail. Once she has the humans' scent, Commander Tryska will never give up the hunt.

4.4 United by Matt Fitton

The Silurians hold Great Britain under siege. Grand Marshal Jastrok rules the seas and the skies with reptile forces. On the ground, Commander Kalana crushes all ape resistance.

With Kate Stewart trapped, defence of the realm falls to UNIT's old guard. Jo Jones, Mike Yates and John Benton are ready to do their duty and stand united.
