The noun clause in the sentence "I heard that the book is set to release soon" is "that the book is set to release soon".

To identify the noun clause, you need to look for a group of words that functions as a noun and is acting as the direct object of the verb "heard". In this case, "that the book is set to release soon" functions as a singular noun that refers to the content of what the speaker heard. It can be replaced with a single noun, such as "information" or "news".
