Son of angels. Jonah Stone

"Jonah's story comes to resemble a modern-day Job as he's faced with trials that affect his health, strength, relationships, and most-prized possessions. As he and the other quarterlings prepare for mid-term exams, their powers are tested once again in the most fierce battle against Abaddon's forces yet. Will Jonah's faith in Elohim continue to persevere as he fights Abaddon in his hardest battle yet?"--Provided by publisher.

Seventh-grader Jonah Stone discovers that he is one-quarter angel--his mother is the daughter of a human and a fallen angel--and when she is kidnapped, Jonah and his sister Eliza must try to rescue her, with the help of prayers and a guardian angel.

When the powers of the Evil One threaten to destroy eighth-grader Jonah and the other humans who are one-quarter angel, Jonah is led by a series of visions to find the one person who is meant to call upon God's faithfulness and save them--a prophet of Elohim.
