Book 4 of Crown Empire Echo Protocol
As Operation Echo Protocol begins, humanity confronts its first true alien structure — buried beneath the Antarctic ice and pulsing with signals no one can decipher. Miriam Varquez and Elijah Meade spearhead the UK-led expedition into the monolith, as political tensions escalate between Britain, China, Russia, and the uneasy members of the international hyperspace consortium. Strange pulses echo across Earth’s electromagnetic field, and orbiting probes detect phantom activity from hyperspace itself.
The monolith is not dead. It is speaking.
