Ionic 4+ / My new book is out, yeah!

After writing nine month (!) my new book about Ionic 4 is out.
But despite its 600 pages, I would like to complete it further. To make the right additions, I’m looking for a power user who reads the book critically and makes suggestions. Interest? Then get in touch and I’ll send you a promo code for free retrieval of the book. Thank you in advance!
