The Aops intermediate algebra text mentioned is at a higher level. It’s not a book I would suggest for summer review. You could try a monthly subscription to Aleks.Com my kid did that the summer before his Algebra 2, and he says it helped. It’s an adaptive program , so you just choose the course you want and the program assesses strengths and weaknesses. You can perhaps review Algebra 1 this way. ALEKS will let you change a course too.
You could also simply review the topics using khan academy along with a standard textbook. Khan academy seems to have improved their interface.
