“Celeste Tunnels Underground” tells the story of young civil engineer Celeste who is tasked with relieving traffic congestion in Dallas, Texas.

She gains inspiration from old and new tunnelling projects, such as the Channel Tunnel and the Fehmarnbelt Tunnel, and using this knowledge, she gives readers a glimpse into tunnel construction and showcases an appreciation for the people who design and build tunnels.

The self-published author and engineer, Courtney Kelly, said “Celeste Tunnels Underground” promotes an early interest in architecture, engineering, and construction by encouraging children to find ways to help their community using STEM.

Kelly is a commercial and heavy civil construction project management professional in Dallas. She holds Bachelor’s degrees in civil engineering and maths, and a Masters in civil engineering from Southern Methodist University. She received an MBA from Lamar University and is a licensed professional engineer in the state of Texas. In 2023 she was recognised as an Engineering News-Record Texas & Louisiana Top Young Professional.

The new book follows the first in the series, Celeste Saves the City, which has been sold in 10 countries in English, German, French and Spanish versions.

Both books are available in hardback, paperback, and eBook.
