Project Mars

Cha Ddeosari, or Plankie, lost her family to an alien attack years ago and is bullied for her unusual name and obsession with aliens. When two mysterious Kudoomians—aliens with pink blood, disguised as humans—appear to capture her, she fights back using a strange power... the ability to control the stars. Outnumbered and outmatched, suddenly a blue alien steps into the fray, offering what might be the chance at friendship she's been searching for her entire life. Will Plankie finally find the ally she needs?
