Walter Foster imprint, it's 40 pages and available in paperback and ebook formats.
The titles in this series are formatted in a similar manner and this one is no exception.
A short general introduction (10%) covers tools and materials including pencils, pens, paper, blending tools, etc. The intro is followed by a group of non-specific tutorials on shading, light, shapes and perspective for types of flowers. Following the intro chapters are 25 flower specific step-by-step tutorials. These are beautiful but -very- simplified. I liked seeing the roughed out first steps, but the last of the first steps (very rough) is followed by the final step which is beautiful but remotely connected (in my case at least) from the previous step.
It's worth noting that the ebook version of the eARC includes a very handy interactive table of contents. I really liked that. Each of the tutorials include 4-6 steps start to finish.
I like these tutorial booklets, they're inexpensive and full of useful info for artists looking for improvement in their own work.
Disclosure: I received an early eARC at no cost from the author/publisher for review purposes.
