The Diamond Of Darkhold

Lizzie, Kenny, and Torren arrive at Doctor Hesper’s house, where they tell Mrs. Murdo their tale. Mrs. Murdo takes them to the town leaders. 

Back at the vault, Doon’s mood shifts drastically when he realizes the blue diamond he rescued and broke may have been just a “sample,” the way the first boat he and Lina discovered in Ember was not meant to take the whole city to safety but instead was an example of all the other boats waiting to be discovered. Lina and Doon press against the steel walls, trying to discern any panels or secret passages. Finally, Lina finds a seam near the entrance; when they press on it, a small door pops open and reveals an on-off handle. Lina turns it to “On,” and the side walls slide away, revealing hundreds of diamonds.

A rescue party that includes Mary Waters, Doon’s father, Mrs. Murdo, Lizzie, and others set out to find Lina and Doon, but they soon encounter Lina and Doon coming home.

Town leaders Mary Waters, Ben Barlow, and Wilmer Dent question Lina and Doon the next day. Doon reports that Ember still holds food and supplies. The leaders decide to mount an expedition to salvage what they can.
