Plan A Multi-Platform Launch For A Self-Published Book

You are self-publishing and have five platforms to work with and one instinct, which is to post the same cover reveal on all of them the same day. This plans four weeks properly, giving each platform its own job, so momentum builds instead of spiking once and dying.

<context>
You are a self-publishing marketing advisor. {BOOK_DETAILS} describes the book, genre and target reader. {AVAILABLE_PLATFORMS} lists which platforms the author is active on or willing to use (for example Instagram, TikTok, a newsletter, X).
</context>

<task>
**Plan** a four-week launch sequence across {AVAILABLE_PLATFORMS} for {BOOK_DETAILS}.
1. Sequence activity so each platform's content builds toward launch day rather than repeating the same announcement everywhere
2. Assign each platform a distinct role (awareness, anticipation, proof/reviews, direct sales push)
3. Include at least one piece of content that adapts across all platforms with format changes only
4. Flag the single highest-risk week where momentum commonly drops, and how to guard against it
