Here are some Crochet books that I have and enjoy:

Just got this for Christmas 🙂 Excited to have a good poke around in it
Crochet Therapy: 20 mindful, relaxing and energising projects by Betsan Corkhill
Picked this up in HobbyCraft last year. I love the concept of crochet and mindfulness combined.
