Wasp Squadron: Publisher's Pack 2 contains Ace (book 3) and Fortitude (book 4) of The Navy of Humanity: Wasp Squadron series.

Ace: book 3

Alien Crystals don't recognize human boundaries; the Navy of Humankind has to hold them back. Small fighters in the vastness of space...the Joint Task Force Iron Shield stands ready. Too small to defend everywhere, they need intel so they can go on the attack and maximize their firepower...and their impact.

The Crystals do not know fear; they are coming for what they want. Wasp pilots are flying because they have to. Only they stand between the Crystals and humanity. Only the Iron Shield can stop the invasion. Be ready. They are coming.

Fortitude: book 4

The aliens arrived and they weren’t looking to make friends. Can Beth fight back the invasion? She has spent her career building a reputation. No one wants to mess with Beth when she’s behind the stick of her fighter, but this time, she’s not flying it. Can the Navy’s biggest badass ace get the job done without her tech?

Now, three years into the struggle, the aliens have made a statement. Blowing up a world has gotten everyone’s attention. The public is terrified, and the Directorate fears the worst. The galaxy needs hero, even if it comes in a small package.
