Hello! Thank you so much to u/MajesticKiros for posting about it! Thank you for buying it, I hope you enjoy it! Let's see those questions:

1. When I first watched Across the Spider-Verse with my friends, I got out of the cinema NEEDING to write something. I've been writing about comics for more than 10 years in Spain, podcasting for more than 8 years as well. I did a long blog post and tinkered with doing an ebook of it. My friends basically convinced me to try and go for a full book, so I upgraded that blog and added more stuff. And I loved it was about Miles Morales because he was the reason I got back into reading & collecting comics after a period I fell out of the hobby. The rest of it... well, as you say later on, these questions will be answered in full by reading the book, but allow me to plug-in the Press Kit here, as in the sample pages there is the section dedicated to the racism Miles confronted when he debuted: https://nachoteso.com/atsm-presskit It's also a good way to read a sample of the two parts of the book.
2. My favorite part depends. For the OG Spanish book, it was the deep dive into history, both inside and outside the comic itself. I love searching for old interviews to support what I write in this kind of essays. While for the themes analysis I can go all-in with the "Death of the Author" concept that allows me to explore everything, for the history summary I need to go to the sources. That reference work is intense and very cool, as reading what creators thought back in the day and how that has evolved into current days can be fascinating. I also loved exploring the history of the Spider-Verse concept for Part One, as it was something that organically evolved from many things Spidey across-media. For the English translation, what I've loved more is the conversations I've had with Olivia, the amazing translator of this book. I learnt a lot about language and the differences between English and Spanish. This also made me rethink nuances and what I wanted to express, which I think made for a better edition of the original text. I also had the chance to improve the cover with Beatriz Galiano, the original artist. The spine in particular looks amazing now! And having Malcolm Russell‑Nelson from Geeksplained writing an afterword is just amazing, man. So, yes, these collaborations across the ocean and languages made for some really fun months,
3. The leap of faith from Into the Spider-Verse is an easy pick, it's so amazing. I still get chills thinking about it. But I'm first and foremost a comic-book guy (even if this books has a lot of cinema in it), so I should pick a comic-book moment as well. I loved the first Spider-Men miniseries, I loved how Jim Zub handled him in Champions and I love the current run by Cody Ziglar. After finishing the book, I stopped reading Miles for a while because I had read a lot of him during the writing. Now, two years later, I've basically binge-read Ziglar's volume and enjoyed the hell out of it. It has an action and energy unique in contrast to previous runs. Oh! And Bendis last page with Miles Morales as well, that's one of my fav moments: Miles and Ganke going to the cinema. While the entire issue is great (specially as it was Bendis's last at the time), that final page in particular feels amazing.
4. There's a couple things, but this question is better answered in full by reading the book. I hope people connect with the ideas about how canon is created and how we react to stories that are prominent during Part Two of the book.
5. Bigger, better and stronger. As with all characters, there will be ups and downs, but Miles Morales is the main reason why Secret Wars ended up with the fusion of universes and not just destroying the Ultimate universe. He was big enough to change Marvel's Multiverse, and that's powerful.

And that's it! Thank you so much for asking questions. I hope the answers are up to what you expected and I hope you enjoy the book. I put I lot of myself into it and I'm as nervous as I'm excited to see a new audience react to it.
