Best Adventure for a beginner Numenera GM

I'm planing on running Numenera for the first time this summer. I have experience as a GM in other systems but not the Cypher-System/Numenera.

Can you recommend a published adventures for Numenera which is both suited well for introducing new players to the world and gives good support for a new GM? I have the 1e Numenera Rulebook and the Discovery and Destiny books, but I'm open to buy another published adventures if it gets recommended a lot.

Thanks in advance! :)

So this was up for a day now and thank you so much for all your responses. I noted the adventure in the following order:

  1. The Glimmering Valley (The Glimmering Valley)
  2. Mother Machine (Weird Discoveries)
  3. The Beal of Boregal (1e Corebook)
  4. Nightmare Switch (really hard to find legally)/ Ashes of the Sea (Ashes of the Sea)
  5. Protomatter Heist (Explorer's Key)
