The Sea Monarch

"The Sea Monarch" by Percy F. Westerman is an early twentieth-century adventure where Sub-Lieutenant Gerald Tregarthen's relaxing leave aboard his friend's yacht takes an unexpected turn. After a collision with a mysterious vessel, Tregarthen finds himself caught up in Captain Brookes's ambitious plan to enforce world peace through unrivaled naval dominance, with the story beginning on a sunny day in Portsmouth Harbour and rapidly escalating as Tregarthen grapples with strange encounters at sea, imprisonment on Brookes's advanced cruiser, and the moral dilemma of supporting a radical vision of peace maintained by force.
