Each of these patterns contain either cluster stitches (smocking) or nupps/bobbles or both. There are many ways described to make bobbles or nupps in the various patterns including the crochet hook method, which is slower, but always shows the bobble/nupp well, and on the right side of the pattern.
The book ranges in patterns from scarves, to rectangular shawls to crescent shawls.
I think you’ll enjoy it, especially at this price for 8 patterns.
