Matthew Sturniolo Announces New Book ‘What Happened Yesterday’

At the moment, only limited official details about the book have been
released publicly. Early descriptions suggest that
What Happened Yesterday will be a personal and reflective project
connected to Matthew Sturniolo’s life, experiences, and perspective as a
creator growing up online.

Because the announcement is still very new, fans are actively speculating
whether the book will be:

• a memoir
• a collection of personal reflections
• behind-the-scenes stories
• mental health discussions
• or autobiographical storytelling

More official information is expected in the coming weeks.

The trend exploded largely because of the massive online fanbase
surrounding the Sturniolo Triplets.

On TikTok and BookTok especially, fans began sharing:

• reaction videos
• edits and aesthetic clips
• theories about the book
• emotional reactions
• and discussions about Matthew’s personal life

Many users were also initially confused about whether the book was:

• real
• a fanfiction project
• or part of a viral Wattpad trend

Once major news outlets started reporting the announcement, interest grew
even faster.

Early fan reactions have been overwhelmingly emotional and excited.

Many longtime viewers say they are curious to see:

• a more vulnerable side of Matthew
• deeper discussions about fame and internet culture
• personal stories never shared in videos

Others are simply excited to support a creator they have followed for
years.

At the same time, some online discussions have questioned whether the
book will mainly appeal to existing fans or also attract general readers.

Right now, the project appears closer to memoir or personal nonfiction
than fiction, although complete official details have not yet been
confirmed.

The title What Happened Yesterday has already sparked fan
speculation around themes including:

• memory
• identity
• growing up online
• relationships
• mental health
• life behind social media fame

The book is expected to release later this year, though exact release
details may vary depending on region and retailer availability.

Fans are already tracking preorder announcements and updates across
social media platforms.
