There is peril beneath the watchful eyes of the Lady...
When Anna Pigeon left New York City after her husband was killed, she hoped it would be forever. But now her sister Molly is clinging to life in an uptown hospital ICU, so Anna has reluctantly returned. Rooming with a friend and fellow park ranger in close quarters on Liberty Island—the small strip of land that is home to Lady Liberty—Anna spends her free time exploring the grand monument and the crumbling, overgrown, and eerie ruins in the unrestored sections of nearby Ellis Island. But the peace she seeks here is shattered when she finds herself among a crowd gathered at the Lady's base, staring at the broken body of a teenager who fell—or was pushed—to her death.
The reason behind the youthful girl's fatal plunge is not the only mystery alive on these historic sites—nor will hers be the only death. Hidden in a dangerous labyrinth of stone, glass, and steel are secrets Anna Pigeon is now compelled to uncover...and an insidious threat to herself and to others that could wreak havoc on a nation's proudest day. There is peril beneath the watchful eyes of the Lady...
