Strength in Struggle — Jonathan Yanez

The aliens are set to obliterate.  Every Knight will be vital.  She leaves home for the academy, perhaps for the last time. Fighting back an invading race has put Earth on the radar of tyrants. While humanity's newly appointed space force peacekeeping branch is formed, it will be up to Emma and her band of fighters to put down the intergalactic bullies of the universe once and for all. The final battle will begin. No one will come out unscathed. Full of fast-paced, fantastic adventure with characters who might make you cry, Strength in Struggle is the third book in the space adventure series The New Arilion Knights.
