There's a whole series of ebooks by Syncfusion that are exactly what you're describing. Matter fact I think they call them the "Succintly" ebooks series because they tend to introduce a technology or topic in a short 100-200 pages. Check em out here: https://www.syncfusion.com/ebooks

At 2.5k a year, I'd rather pay for Pluralsight or something similar. That's an amazingly huge price for an individual-focused training.

I'm seeing free E-books. That $2.5k must refer to their services.

I just downloaded a free book. In the intro it says:

> Free forever. Syncfusion will be working to produce books on several topics. The books will always be free. Any updates we publish will also be free.
